Title
Apache Camel: Camel-Netty-HTTP: The muteException consumer option defaulted to false, so a processing error returned the full Java stack trace in the HTTP response body, disclosing sensitive internal information to unauthenticated clients
Summary
Generation of Error Message Containing Sensitive Information vulnerability in Apache Camel Netty HTTP component. The camel-netty-http HTTP server consumer exposes a muteException option that controls what is returned to the client when a route processing error occurs. This option defaulted to false because the backing field was an uninitialised primitive boolean (Java's default of false), whereas the other Camel HTTP server components (camel-http / camel-jetty / camel-servlet and camel-platform-http) default it to true. With muteException=false, when a request triggers an exception during route processing the consumer writes the full Throwable stack trace into the HTTP response body as text/plain (via DefaultNettyHttpBinding) instead of returning an empty body. Any unauthenticated client that can reach the endpoint and cause a processing error - for example by sending a malformed request body, an invalid parameter, or otherwise triggering a route-internal failure - therefore receives a complete Java stack trace. Such a stack trace can disclose sensitive internal information, including credentials embedded in exception messages, internal host names and IP addresses, filesystem paths, dependency and version details, database and class names, and the application's internal structure, which an attacker can use to plan further attacks. This issue affects Apache Camel: from 4.0.0 before 4.14.8, from 4.15.0 before 4.18.3, from 4.19.0 before 4.21.0. Users are recommended to upgrade to version 4.21.0, which fixes the issue. If users are on the 4.14.x LTS releases stream, then they are suggested to upgrade to 4.14.8. If users are on the 4.18.x releases stream, then they are suggested to upgrade to 4.18.3. For deployments that cannot upgrade immediately, set muteException=true explicitly on the camel-netty-http consumer (for example netty-http: http://0.0.0.0:8080/api?muteException=true , or globally via the camel.component.netty-http.configuration.mute-exception=true property), so that processing errors no longer return the stack trace to the client.

CVE-2026-47775 (GCVE-0-2026-47775)

Vulnerability from cvelistv5 – Published: 2026-06-26 17:23 – Updated: 2026-06-29 15:20

Title
Envoy OAuth2 Filter: Padding Oracle via AES-256-CBC Cookie Decryption
Summary
Envoy is an open source edge and service proxy designed for cloud-native applications. Prior to 1.35.11, 1.36.7, 1.37.3, and 1.38.1, the OAuth2 HTTP filter's encrypt()/decrypt() functions use AES-256-CBC without an authentication tag (no HMAC, no AEAD). The /callback endpoint returns HTTP 302 on successful decryption and HTTP 401 on padding failure, creating a padding oracle. An attacker who obtains the encrypted CodeVerifier cookie can recover the plaintext PKCE code_verifier in ~6,200 requests (~100 seconds), then exchange it with a stolen authorization code to obtain the victim's access token. This vulnerability is fixed in 1.35.11, 1.36.7, 1.37.3, and 1.38.1.

CVE-2026-47248 (GCVE-0-2026-47248)

Title
Parse Server: GraphQL "Did you mean" validation suggestions disclose schema to unauthenticated callers
Summary
Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.78 and 9.9.1-alpha.2, Parse Server's GraphQL endpoint discloses schema metadata to unauthenticated callers through Did you mean ...? suggestions embedded in GraphQL validation-error messages. An unauthenticated caller who knows only the public application id can iteratively send malformed queries to reconstruct class names, field names, argument names, mutation names, and input-object fields. This issue has been patched in versions 8.6.78 and 9.9.1-alpha.2.

CVE-2026-45728 (GCVE-0-2026-45728)

Vulnerability from cvelistv5 – Published: 2026-05-26 16:38 – Updated: 2026-05-26 17:31

Title
Algernon: Single-file mode unconditionally enables debug mode
Summary
Algernon is a small self-contained pure-Go web server. Prior to 1.17.7, when Algernon is invoked with a single file path instead of a directory, singleFileMode is set to true and debugMode is forcibly enabled. debugMode activates the PrettyError renderer, which on any Lua or template error response dumps the absolute path of the file that errored, complete byte contents of that file, and exception or parser error text. This response is served with HTTP 200 OK to whoever sent the request that triggered the error. Any client able to reach the server and able to provoke a runtime error in the served script obtains the full server-side source of that script and of any sibling Lua data file consulted during the request. This vulnerability is fixed in 1.17.7.

Title
pyLoad: Unauthenticated traceback disclosure via global exception handler in WebUI
Summary
pyLoad is a free and open-source download manager written in Python. Prior to 0.5.0b3.dev100, pyload-ng WebUI returns full Python traceback details to clients on unhandled exceptions. Because /web/<path:filename> is reachable without authentication and renders attacker-controlled template names, an unauthenticated user can reliably trigger a server exception (for example by requesting a non-existent template) and receive internal stack traces in the HTTP response. This vulnerability is fixed in 0.5.0b3.dev100.

Title
vm2: Host File Path Disclosure via Stack Trace Information Leak
Summary
vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.0, vm2's CallSite wrapper class (intended as a safe wrapper for V8's native CallSite) blocks getThis() and getFunction() to prevent host object leakage, but allows getFileName() to return unsanitized host absolute paths. Any sandboxed code can extract the full directory structure, library paths, and framework versions of the host server. This vulnerability is fixed in 3.11.0.

Title
WWBN AVideo: Unauthenticated Disclosure of CloneSite `myKey` via Error Echo in `cloneClient.json.php` Enables Cross-Site DB Dump of the Configured Clone Server
Summary
WWBN AVideo is an open source video platform. In versions up to and including 29.0, plugin/CloneSite/cloneClient.json.php echoes the local CloneSite shared secret ($objClone->myKey, a constant md5($global['systemRootPath'] . $global['salt'])) into the HTTP response body on every unauthenticated request. The unauthenticated error branch was intended to reject non-admin callers without a valid key, but the rejection message interpolates the expected key before die(). When the victim has CloneSite configured with a remote cloneSiteURL (standard federation/backup setup), the leaked myKey is exactly the credential that authenticates the victim to that remote server's cloneServer.json.php, allowing the attacker to impersonate the victim and trigger a full mysqldump of the remote's database to the remote's public videos/clones/ directory Commit e6566f56a28f4556b2a0a09d03717a719dcb49da contains an updated fix.

Title
llama.cpp b5702–b7653 Out-of-Bounds Read Information Disclosure
Summary
llama.cpp builds b5702 through b7653 contain an out-of-bounds read vulnerability in the recurrent memory state restore path that allows attackers with write access to the slot save directory to read memory past the end of the allocated cells array. Attackers can craft a malicious slot file with an oversized seq_id value to trigger an out-of-bounds read that leaks heap data including pointer values into server logs, defeating ASLR protections and facilitating further exploitation.

CVE-2026-42552 (GCVE-0-2026-42552)

Vulnerability from cvelistv5 – Published: 2026-05-13 19:24 – Updated: 2026-05-15 18:49

Title
Flight: Sensitive information disclosure via default error handler in flightphp/core
Summary
Flight is an extensible micro-framework for PHP. Prior to 3.18.1, the default error handler Engine::_error() writes the full exception message, exception code, and stack trace (including absolute filesystem paths) directly into the HTTP 500 response, with no debug gating. Production deployments leak internal paths, any secret interpolated into an exception message, and full module structure — giving attackers primitives for chaining other weaknesses (LFI, path traversal). This vulnerability is fixed in 3.18.1.

Mitigation MIT-39
Implementation
  • Ensure that error messages only contain minimal details that are useful to the intended audience and no one else. The messages need to strike the balance between being too cryptic (which can confuse users) or being too detailed (which may reveal more than intended). The messages should not reveal the methods that were used to determine the error. Attackers can use detailed information to refine or optimize their original attack, thereby increasing their chances of success.
  • If errors must be captured in some detail, record them in log messages, but consider what could occur if the log messages can be viewed by attackers. Highly sensitive information such as passwords should never be saved to log files.
  • Avoid inconsistent messaging that might accidentally tip off an attacker about internal state, such as whether a user account exists or not.
Mitigation
Implementation

Handle exceptions internally and do not display errors containing potentially sensitive information to a user.

Mitigation MIT-33
Implementation

Strategy: Attack Surface Reduction

Use naming conventions and strong types to make it easier to spot when sensitive data is being used. When creating structures, objects, or other complex entities, separate the sensitive and non-sensitive data as much as possible.

Mitigation MIT-40
Implementation Build and Compilation

Strategy: Compilation or Build Hardening

Debugging information should not make its way into a production release.

Mitigation MIT-40
Implementation Build and Compilation

Strategy: Environment Hardening

Debugging information should not make its way into a production release.

Mitigation
System Configuration

Where available, configure the environment to use less verbose error messages. For example, in PHP, disable the display_errors setting during configuration, or at runtime using the error_reporting() function.

Mitigation
System Configuration

Create default error pages or messages that do not leak any information.

CAPEC-215: Fuzzing for application mapping

An attacker sends random, malformed, or otherwise unexpected messages to a target application and observes the application's log or error messages returned. The attacker does not initially know how a target will respond to individual messages but by attempting a large number of message variants they may find a variant that trigger's desired behavior. In this attack, the purpose of the fuzzing is to observe the application's log and error messages, although fuzzing a target can also sometimes cause the target to enter an unstable state, causing a crash.

CAPEC-463: Padding Oracle Crypto Attack

An adversary is able to efficiently decrypt data without knowing the decryption key if a target system leaks data on whether or not a padding error happened while decrypting the ciphertext. A target system that leaks this type of information becomes the padding oracle and an adversary is able to make use of that oracle to efficiently decrypt data without knowing the decryption key by issuing on average 128*b calls to the padding oracle (where b is the number of bytes in the ciphertext block). In addition to performing decryption, an adversary is also able to produce valid ciphertexts (i.e., perform encryption) by using the padding oracle, all without knowing the encryption key.

CAPEC-54: Query System for Information

An adversary, aware of an application's location (and possibly authorized to use the application), probes an application's structure and evaluates its robustness by submitting requests and examining responses. Often, this is accomplished by sending variants of expected queries in the hope that these modified queries might return information beyond what the expected set of queries would provide.

CAPEC-7: Blind SQL Injection

Blind SQL Injection results from an insufficient mitigation for SQL Injection. Although suppressing database error messages are considered best practice, the suppression alone is not sufficient to prevent SQL Injection. Blind SQL Injection is a form of SQL Injection that overcomes the lack of error messages. Without the error messages that facilitate SQL Injection, the adversary constructs input strings that probe the target through simple Boolean SQL expressions. The adversary can determine if the syntax and structure of the injection was successful based on whether the query was executed or not. Applied iteratively, the adversary determines how and where the target is vulnerable to SQL Injection.
