Technical description

In Splunk Enterprise versions below 10.4.3, 10.2.7, 10.0.10, and 9.4.15 on Linux, a local user who can run commands as the user account running Splunk Enterprise could cause an affected Linux package upgrade to run attacker-controlled operating-system commands with root privileges. The vulnerability is possible because the Linux package maintainer script trusts existing Splunk Enterprise installation content when it performs upgrade operations with root privileges. The vulnerability requires an affected Linux package upgrade to occur after the local user modifies the installation. The local user should not be able to elevate privileges at will.

——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.10h CVE-2026-942688.1 HIG

——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.5h CVE-2026-1119827.2 HIG

——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
