Description
Jenkins Eiffel Broadcaster Plugin 2.8.0 through 2.10.2 (both inclusive) uses the credential ID as the cache key during signing operations, allowing attackers able to create a credential with the same ID as a legitimate one in a different credentials store to sign an event published to RabbitMQ with the legitimate credentials.

Vendor / applianceDetect
Inventory every jenkins eiffel broadcaster deployment and check each version against the affected-products list above. Because the exploit targets the running system rather than your application code, also watch for exploitation at the network and runtime layer — O3 flags the exploit behaviour from runtime telemetry and egress traffic even before a vulnerable build is confirmed.
Remediation status
No patch has shipped for CVE-2025-24400 yet — track the jenkins eiffel broadcaster advisory for a fixed release and apply the workarounds below in the meantime.
Mitigate without a patch
Cut exposure now: restrict the management/admin interface to trusted networks, segment the device, and apply the vendor's recommended configuration mitigations and any WAF/IPS signature. O3's runtime protection blocks the exploit chain at execution, holding the line on unpatched or end-of-life systems until you can patch.
How O3 protects you
O3 detects and blocks CVE-2025-24400 exploitation at runtime: eBPF exploit-chain detection, plus L7 egress monitoring that catches the post-exploitation callback and severs the attacker's outbound channel.
Tailored to CVE-2025-24400. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
