Descripción técnica

Incorrect Authorization (CWE-863) in project name normalization (ProjectUtil.stripGitSuffix) and ProjectCache eviction logic (ProjectCacheImpl) in Gerrit Code Review versions 2.16.0 through 3.12.9, 3.13.0 through 3.13.8, and 3.14.0 through 3.14.2 allows an authenticated user (or an unauthenticated user if the repository was previously public) to cause unauthorized disclosure of private repository content and durable restoration of revoked project-owner administrative privileges via crafted requests using repeated .git suffixes (such as project.git.git) across REST APIs, Gitiles, or SSH Git commands. Because Gerrit strips only a single terminal .git suffix when constructing the logical ProjectCache key while JGit (FileKey.lenient) resolves the suffixed alias to the same canonical bare repository on disk, revoking read access or removing owner rules on the canonical project name fails to evict the cached alias ProjectState during the cache validity window, enabling reads of newly created private commits or writes to refs/meta/config. This issue is fixed in Gerrit Code Review versions 3.12.10, 3.13.9, and 3.14.3.

——0BerriAI LiteLLM before 1.101.0-rc.1 contains a tenant isolation bypass vulnerability in the semantic cache layer that allows authenticated users to read other tenants' cached responses by exploiting a metadata key mismatch between _get_semantic_cache_tenant_scope() and _get_metadata_variable_name(). Attackers holding a valid virtual key can submit semantically similar prompts on affected routes such as /v1/responses and /bedrock/* to retrieve cached responses containing other tenants' personally identifiable information, financial data, or source code, and can cause agentic front-ends to auto-execute attacker-supplied tool calls under victim credentials by returning cached function_call or tool_calls payloads to a different principal.39m CVE-2026-67411—

——0RabbitMQ is a messaging and streaming broker. From 3.13.0 until 3.13.18, 4.0.23, 4.1.14, 4.2.9, and 4.3.3, native MQTT and MQTT over WebSocket behind a trusted PROXY Protocol frontend could lose the proxy-derived client address before the MQTT authentication path checked loopback_users, causing the frontend-to-broker address to be treated as loopback. An attacker who can reach the trusted frontend and has valid credentials for a loopback-restricted account can therefore bypass the source-address restriction; the issue does not bypass password authentication. This issue is fixed in versions 3.13.18, 4.0.23, 4.1.14, 4.2.9, and 4.3.3.39m CVE-2026-67242—

——0RabbitMQ is a messaging and streaming broker. From 4.2.0 until 4.2.9 and 4.3.3, OAuth2 isinteger(Exp) guard skips token-expiry checks for float exp. validatetokenexpiry/1 (lines 208-214) and expirytimestamp/1 (138-144) both guard with 'when isinteger(Exp)' and fall through to ok/never for float values. josejwt:verify validates only the signature, not exp. With float exp, no expiry validation occurs anywhere in the If the IdP emits exp as a JSON float (RFC 7519 permits fractional NumericDate), both the login-time expiry check and the mid-connection disconnect timer are silently skipped , an already-expired token is accepted, and connections never time OAuth2 backend enabled IdP emits float exp (uncommon; mainstream IdPs emit integers) Attacker possesses a previously-valid signed. This issue is fixed in versions 4.2.9 and 4.3.3.39m CVE-2026-56723—

——0Zammad is a web based open source helpdesk/customer support system. Prior to 7.0.2, a customer who can view a ticket cannot see internal ticket articles through the article listing API. However, the same customer can directly request an attachment belonging to an internal article via the attachment download endpoint, bypassing article-level authorization. This results in an inconsistency: The article listing hides internal articles from customers. The attachment download only checks the parent ticket, not the article, so the same customer can download the attachment directly. This issue is fixed in version 7.0.2.39m CVE-2026-936439.8 CRÍ
