Descripción técnica

Vikunja is an open-source self-hosted task management platform. In version 2.3.0, a scoped API token limited to the `oauth.authorize` permission can call `POST /api/v1/oauth/authorize`, obtain an OAuth authorization code, and exchange the code at `POST /api/v1/oauth/token` for a normal bearer JSON Web Token (JWT) and refresh token. The resulting credentials are not restricted by the original API token's permissions, allowing access to routes outside its declared scope for the same user. Version 2.4.0 fixes the vulnerability.

——8Initialization of a Resource with an Insecure Default vulnerability in Hallo Welt! GmbH BlueSpice (container image bluespice/wiki) allows privilege escalation. The default value of $mwsgTokenAuthenticatorServiceCIDR in the container's LocalSettings.php was intended to restrict internal service authentication to the container network, but evaluated to an empty string when the environment variable WIKI_SERVICE_TOKEN_AUTH_ALLOWED was not set. An empty value disables the IP restriction in the token authenticator component (mwstake/mediawiki-component-token-authenticator). As a result, any user with read access to the wiki (anonymous users on publicly readable wikis) could obtain an application token from the REST API and use it to get a session with sysop privileges as the internal service user. This issue affects BlueSpice: from 5.2.3 before 5.2.7, and the 5.2.7 container images published before 2026-10-19 15:37 UTC.13h CVE-2026-942688.1 ALT

——2The Advanced Custom Fields: Extended WordPress plugin before 0.9.2.8, Advanced Custom Fields: Extended PRO WordPress plugin before 0.9.2.8 does not resolve the target of the update-user action in its front-end Forms module consistently between the stage that authorises the request and the stage that carries it out, which allows unauthenticated visitors to bypass the guard protecting administrator accounts, take over the site administrator's account and be issued a valid session for it. Exploitation requires the site to publish two separate front-end form configurations whose targets are mapped to visitor-submitted values.8h CVE-2026-1119827.2 ALT

——4LiteLLM is a proxy server (AI Gateway) to call LLM APIs in OpenAI (or native) format. From 1.87.0 until 1.100.4, 1.101.3, 1.102.2, 1.103.1, and 1.104.0-rc.2, the proxy reuses one cryptographic context for at-rest secrets and session tokens, allowing an authenticated internal user to have crafted metadata containing a forged administrator credential encrypted and returned by the API-key flow. Replaying that ciphertext as a bearer token causes the proxy to trust the forged proxy administrator identity, permitting administrative access and arbitrary commands through the MCP stdio endpoint. Versions 1.87.0 through 1.90.x require EXPERIMENTAL_UI_LOGIN to be enabled, while versions after 1.91.0 are exploitable in the default configuration. This issue was fixed in LiteLLM 1.100.4, 1.101.3, 1.102.2, 1.103.1, and 1.104.0-rc.2.1d
