Signature threshold validation bypass in go-tuf versions 2.0.0 through 2.3.0 allows a compromised or misconfigured TUF repository to disable signature verification by setting thresholds to zero, enabling attackers to tamper with metadata files without detection. This affects systems relying on go-tuf for secure software update verification, potentially allowing unauthorized modifications to trusted metadata both at rest and in transit. A patch is available in version 2.3.1.

go-tuf is a Go implementation of The Update Framework (TUF). [CVSS 5.9 MEDIUM]

Seroval versions 1.4.0 and below are vulnerable to denial of service through malformed deserialization payloads that specify excessively large array lengths, causing the parsing process to consume excessive CPU resources and become unresponsive. An unauthenticated remote attacker can exploit this without user interaction by sending a crafted serialized object to any application using the vulnerable library. The vulnerability has been patched in version 1.4.1.

ImageMagick and Magick.NET versions 14.10.1 and below are vulnerable to denial of service attacks through a null pointer dereference in the MSL parser when processing malformed comment tags, exploitable by authenticated attackers without user interaction. Public exploit code exists for this vulnerability, and affected systems may crash or experience assertion failures depending on build configuration. No patch is currently available to address this medium-severity issue.

Privilege escalation in openCryptoki 2.3.2+ allows token-group members to exploit insecure symlink handling in group-writable token directories, enabling file operations on arbitrary filesystem targets when the library runs with elevated privileges. An attacker with token-group membership can plant symlinks to redirect administrative operations, potentially leading to privilege escalation or unauthorized data access. A patch is available.

The resolveSafeChildPath function in Backstage's backend-plugin-api prior to version 0.1.17 improperly validates symlink chains and dangling symlinks, allowing authenticated attackers to bypass path traversal protections used by Scaffolder actions and other backend components. An attacker with low privileges could exploit this to access files outside the intended directory boundaries by chaining intermediate symlinks or creating symlinks pointing to non-existent paths that are later materialized during file operations. This affects Backstage installations relying on the vulnerable path validation function for security isolation.

Arbitrary code execution in Seroval versions 1.4.0 and below allows authenticated attackers to execute malicious JavaScript through improper deserialization handling in the fromJSON and fromCrossJSON functions. Exploitation requires multiple requests to the affected function and partial knowledge of runtime data usage, but grants full code execution capabilities. A patch is available in version 1.4.1 and later.

Seroval is affected by improperly controlled modification of object prototype attributes (prototype pollution) (CVSS 7.3).

When passing data to the b64decode(), standard_b64decode(), and urlsafe_b64decode() functions in the "base64" module the characters "+/" will always be accepted, regardless of the value of "altchars" parameter, typically used to establish an "alternative base64 alphabet" such as the URL safe alphabet. [CVSS 5.3 MEDIUM]

Apache Solr 8.6 through 9.10.0 in standalone mode fails to properly validate the "create core" API parameters, allowing authenticated users to bypass the allowPaths security restriction and access unauthorized filesystem locations. On Windows systems configured with UNC path support, this vulnerability can lead to NTLM credential hash disclosure. Affected deployments using the allowPaths setting are at risk of unauthorized core creation and information exposure.

Unauthorized API access in Apache Solr 5.3.0 through 9.10.0 allows unauthenticated attackers to bypass the RuleBasedAuthorizationPlugin due to insufficient input validation in permission rule enforcement. This vulnerability affects only deployments using multiple roles with specific predefined permissions like config-read, config-edit, schema-read, metrics-read, or security-read without the "all" permission rule defined. Successful exploitation grants attackers unauthorized access to sensitive Solr APIs, potentially exposing configuration and security data.
