Mediawiki Wikilambda Extension
Monthly
Authentication bypass in the Wikimedia Foundation's WikiLambda extension for MediaWiki allows unauthenticated remote attackers to circumvent access controls via improper neutralization of input terminator characters (CWE-288). Affected are all WikiLambda deployments running versions prior to 1.43.9, 1.44.6, and 1.45.4 across the supported MediaWiki release branches. No public exploit or CISA KEV listing has been identified at time of analysis, though the network-accessible, zero-prerequisite attack vector warrants prompt patching.
