CVE-2026-116870 (GCVE-0-2026-116870)

Vulnerability from cvelistv5 – Published: 2026-10-27 10:28 – Updated: 2026-10-27 10:28
VLAI
Summary
In affected versions of Octopus Server, OIDC token issuer validation was performed inconsistently. This could result in a token issued from a suitably configured non legitimate issuer being accepted as a token belonging to a service account from a legitimate trusted issuer. Exploitation requires a service account with at least one OIDC identity configured. An attacker would also need to know or guess some details of that identity in order to be in a position to attempt exploitation.

Title
Contrast 1.21.0 before 1.25.0 Credential Leak via imagepuller Wildcard Registry Selection
Summary
Edgeless Systems Contrast from 1.21.0 before 1.25.0 contains a non-deterministic registry selection flaw in imagepuller that can prefer wildcard configuration entries over concrete domain matches. When a pull configuration lists both a concrete domain and its parent wildcard, registry credentials, CA bundles, or mirror settings intended for the wildcard may be applied to the concrete registry, leaking credentials or pull metadata.

CVE-2026-114348 (GCVE-0-2026-114348)

Title
webpack-dev-server vulnerable to information disclosure via Host validation bypass in the open-editor endpoint
Summary
webpack-dev-server is a development server that provides live reloading for webpack projects. In versions from 5.1.0 before 5.2.7 and in version 6.0.0, the unauthenticated open-editor endpoint validates the Host header with a regular expression meant for browser Origin schemes, so a Host value beginning with file: or with an extension scheme short-circuits the hostname and allowedHosts checks. A network peer that can reach the dev server can send a request with a malformed Host that passes validation and then causes the endpoint's URL construction to throw, and in the default non-production mode the server returns an HTTP 500 body containing the full exception stack trace, which discloses absolute filesystem paths, installed module locations, and internal source line numbers. The server keeps running, so there is no denial of service. The issue is fixed in webpack-dev-server 5.2.7 and 6.1.0, and users should upgrade to one of those versions or later.

CVE-2026-107289 (GCVE-0-2026-107289)

Title
Pydantic AI: SSRF cloud-metadata blocklist bypass via IPv6 zone identifier (incomplete fix for CVE-2026-46678 and CVE-2026-48782)
Summary
Pydantic AI is a Python agent framework for building applications and workflows with Generative AI. From 1.56.0 until 1.107.6 and 2.44.0, applications that opt attacker-influenced URLs into local network access through FileUrl with force_download='allow-local' or web_fetch_tool with allow_local_urls=True can bypass the cloud-metadata blocklist by appending an IPv6 zone identifier to an IPv6 metadata address. IPv6Address equality and hashing include the zone identifier, so the blocklist comparison fails even though the network stack ignores the zone on a non-link-local destination and reaches the metadata service, potentially exposing cloud IAM credentials. The opt-in settings are disabled by default, and the issue requires an IPv6-enabled environment. This issue is fixed in versions 1.107.6 and 2.44.0.

Title
Pydantic AI: web_fetch_tool blocked_domains bypass via a hostname the resolver normalizes differently
Summary
Pydantic AI is a Python agent framework for building applications and workflows with Generative AI. From 1.77.0 until 1.107.6 and 2.44.0, the local web_fetch_tool and the WebFetch local fallback compare blocked_domains entries with a URL hostname before both values are normalized to the form used by getaddrinfo. An attacker-influenced model can use an equivalent IDNA spelling, non-ASCII label separator, case variation, or trailing root label that resolves to a blocked host but does not match the configured string, causing the application to fetch that host with its own privileges. allowed_domains fails closed for unmatched spellings, and private-IP and cloud-metadata protections remain effective. This issue is fixed in versions 1.107.6 and 2.44.0.

CVE-2026-106445 (GCVE-0-2026-106445)

Vulnerability from cvelistv5 – Published: 2026-10-06 19:39 – Updated: 2026-10-12 14:33
VLAI
Title
Handlebars: JavaScript Injection via Own Property Check Bypass
Summary
Handlebars provides the power necessary to let users build semantic templates. From 3.0.0 until 4.7.10, Handlebars lookupProperty returns Function.prototype.constructor before applying the prototype-access deny list because constructor is an own property of Function.prototype. When an attacker can render a controlled template with allowProtoMethodsByDefault enabled and an accessible function in the template context, the template can traverse from that function through its prototype to Function.prototype and then obtain the Function constructor through the own-property bypass. This permits attacker-controlled JavaScript to execute with the server application's privileges. This issue is fixed in version 4.7.10.

CVE-2026-102478 (GCVE-0-2026-102478)

Vulnerability from cvelistv5 – Published: 2026-10-07 01:17 – Updated: 2026-10-07 18:40
VLAI
Summary
In affected versions of Octopus Server, an authenticated user with permission to modify roles could bypass the protections preventing access abuse resulting in privilege escalation. It was possible for the built-in role to be weakened and the attacker's account added to a privileged team. This was achievable due to improper validation of unsafe equivalence in inputs.

CVE-2026-100837 (GCVE-0-2026-100837)

Title
Edgeless Systems Contrast through 1.20.0 Credential Leak via Registry Suffix Matching
Summary
Contrast (Edgeless Systems) through 1.20.0 performs unanchored suffix matching when selecting per-registry configuration in the imagepuller. Config.registryFor strips a single trailing dot and then uses strings.HasSuffix(hostname, fqdn) without requiring a DNS label boundary, so a registry entry such as [registries."ghcr.io."] is also applied to any host whose name merely ends in that byte sequence, including attacker-registered domains such as evilghcr.io. When an image or layer is pulled from such a sibling domain, the imagepuller sends the configured Authorization header (basic auth, registry token, or identity token), trusts the configured custom CA bundle, follows the configured mirror, and honours insecure-skip-verify (disabling TLS verification) for that host. Image integrity is not affected, as image bytes remain pinned by digest in the policy and are validated after the pull. Configurations that use a leading dot (e.g., [registries.".example.registry"]) are unaffected.

Mitigation MIT-5
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.
