Title
Handlebars.java: Arbitrary file read in `SpringTemplateLoader` via URL-fragment suffix bypass
Summary
Handlebars.java provides logic-less and semantic Mustache templates with Java. Prior to 4.5.3, com.github.jknack.handlebars.springmvc.SpringTemplateLoader resolves attacker-influenced Spring MVC view names through Spring ResourceLoader without the path-containment validation used by other URL-based loaders. In handlebars-springmvc/src/main/java/com/github/jknack/handlebars/springmvc/SpringTemplateLoader.java, a view name using a file: or classpath: URL and ending with the # fragment delimiter places the appended .hbs suffix in the fragment, which FileUrlResource.exists() and URL.openStream() discard. HandlebarsViewResolver in handlebars-springmvc/src/main/java/com/github/jknack/handlebars/springmvc/HandlebarsViewResolver.java then passes the attacker-controlled name to handlebars.compile(), allowing an unauthenticated remote attacker to read files accessible to the JVM when an application exposes a controller with a user-influenced view name. This issue is fixed in version 4.5.3.

Title
Path Traversal in Quick.CMS
Summary
A Path Traversal vulnerability exists in Quick.CMS through the URI path component of HTTP requests, where the server fails to normalize dot-dot-slash (../) sequences before resolving and serving the requested file. An authenticated attacker with admin privileges can use this vulnerability to read contents of files located in the sibling directory of the webroot via a crafted HTTP request containing ../ sequences in the URI. The vendor assessed the likelihood of exploitation as very low and determined that a fix is not necessary.

CVE-2026-62843 (GCVE-0-2026-62843)

Vulnerability from cvelistv5 – Published: 2026-07-15 15:42 – Updated: 2026-07-15 16:32

Title
File Browser: Archive builder turns backslash filenames into path traversal (zip-slip)
Summary
File Browser is a file managing interface for uploading, deleting, previewing, renaming, and editing files within a specified directory. From 2.63.6 to 2.63.16, File Browser's archive builder uses strings.ReplaceAll(nameInArchive, "\", "/"), which turns a POSIX filename such as ..\..\evil.sh into the archive entry ../../evil.sh, allowing a user with upload permission to plant a backslash-named file that escapes the extraction directory when another user downloads and extracts the generated zip or tar archive. This issue is fixed in version 2.63.17.

CVE-2026-60093 (GCVE-0-2026-60093)

Title
Apache Camel: Camel-Azure-Storage-DataLake: the downloadToFile operation built the local download target from the remote path name without constraining it to the configured fileDir
Summary
Relative path traversal vulnerability in Apache Camel Azure-Storage Datalake component This issue affects Apache Camel: from 4.0.0 before 4.14.9, from 4.15.0 before 4.18.4, from 4.19.0 before 4.22.0. The camel-azure-storage-datalake component can download an Azure Data Lake Storage Gen2 file to the local filesystem through its downloadToFile operation, writing into the directory named by the fileDir endpoint option. DataLakeFileOperations.downloadToFile built the local target by joining fileDir with the remote path name exactly as the Azure SDK reported it (new File(fileDir, fileClientWrapper.getFileName())) and passed the result straight to the SDK download call, with no lexical normalization and no check that the resolved location stayed inside fileDir. The remote name is not route-controlled data: the consumer enumerates the filesystem in DataLakeConsumer.createBatchExchangesFromPath, which lists paths and creates one exchange per entry from PathItem.getName() verbatim, applying no name filtering by default. A path name containing parent-directory segments therefore resolved to a location outside the configured fileDir, letting anyone able to influence the names present in the consumed Data Lake filesystem cause Camel to create or overwrite a file at a location of their choosing, with the privileges of the Camel process. Depending on what the process can write to, overwriting a file outside the download directory can escalate beyond the loss of integrity of that file. The fileDir option is an ordinary common-group configuration parameter and carries no security marker, so nothing signalled to users that its value was not being enforced as a containment boundary. Camel's other file-download consumers - camel-file, camel-ftp, camel-smb, camel-mina-sftp and camel-azure-files - already constrained their local downloads to the configured directory using a path-segment boundary check; the camel-azure-storage-datalake download path was not covered by that work. Users are recommended to upgrade to version 4.22.0, which fixes the issue. If users are on the 4.14.x LTS releases stream, then they are suggested to upgrade to 4.14.9. If users are on the 4.18.x releases stream, then they are suggested to upgrade to 4.18.4. For deployments that cannot upgrade immediately, constrain the names the consumer will act on using the regex endpoint option, which is applied to each listed path name as a full-string match, so that only simple single-segment names are accepted and any name carrying a path separator or a parent-directory segment is filtered out before an exchange is created. Alternatively, avoid the downloadToFile operation on untrusted filesystems and write the payload from the route under a file name the route itself controls, rather than one taken from the remote listing. As defence in depth, treat the object names in any externally writable Data Lake filesystem as untrusted input and do not derive local filesystem paths from them.

Mitigation MIT-5.1
Implementation

Strategy: Input Validation

  • Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
  • When performing input validation, consider all potentially relevant properties, including length, type of input, the full range of acceptable values, missing or extra inputs, syntax, consistency across related fields, and conformance to business rules. As an example of business rule logic, "boat" may be syntactically valid because it only contains alphanumeric characters, but it is not valid if the input is only expected to contain colors such as "red" or "blue."
  • Do not rely exclusively on looking for malicious or malformed inputs. This is likely to miss at least one undesirable input, especially if the code's environment changes. This can give attackers enough room to bypass the intended validation. However, denylists can be useful for detecting potential attacks or determining which inputs are so malformed that they should be rejected outright.
  • When validating filenames, use stringent allowlists that limit the character set to be used. If feasible, only allow a single "." character in the filename to avoid weaknesses such as CWE-23, and exclude directory separators such as "/" to avoid CWE-36. Use a list of allowable file extensions, which will help to avoid CWE-434.
  • Do not rely exclusively on a filtering mechanism that removes potentially dangerous characters. This is equivalent to a denylist, which may be incomplete (CWE-184). For example, filtering "/" is insufficient protection if the filesystem also supports the use of "\" as a directory separator. Another possible error could occur when the filtering is applied in a way that still produces dangerous data (CWE-182). For example, if "../" sequences are removed from the ".../...//" string in a sequential fashion, two instances of "../" would be removed from the original string, but the remaining characters would still form the "../" string.

Implementation

Strategy: Input Validation

  • Inputs should be decoded and canonicalized to the application's current internal representation before being validated (CWE-180). Make sure that the application does not decode the same input twice (CWE-174). Such errors could be used to bypass allowlist validation schemes by introducing dangerous inputs after they have been checked.
  • Use a built-in path canonicalization function (such as realpath() in C) that produces the canonical version of the pathname, which effectively removes ".." sequences and symbolic links (CWE-23, CWE-59). This includes:
  • realpath() in C
  • getCanonicalPath() in Java
  • GetFullPath() in ASP.NET
  • realpath() or abs_path() in Perl
  • realpath() in PHP
Mitigation MIT-29
Operation

Strategy: Firewall

Use an application firewall that can detect attacks against this weakness. It can be beneficial in cases in which the code cannot be fixed (because it is controlled by a third party), as an emergency prevention measure while more comprehensive software assurance measures are applied, or to provide defense in depth [REF-1481].

CAPEC-139: Relative Path Traversal

An attacker exploits a weakness in input validation on the target by supplying a specially constructed path utilizing dot and slash characters for the purpose of obtaining access to arbitrary files or resources. An attacker modifies a known path on the target in order to reach material that is not available through intended channels. These attacks normally involve adding additional path separators (/ or \) and/or dots (.), or encodings thereof, in various combinations in order to reach parent directories or entirely separate trees of the target's directory structure.

CAPEC-76: Manipulating Web Input to File System Calls

An attacker manipulates inputs to the target software which the target software passes to file system calls in the OS. The goal is to gain access to, and perhaps modify, areas of the file system that the target software did not intend to be accessible.
