CVE-2025-24976
Distribution is a toolkit to pack, ship, store, and deliver container content.
Overview
CVE-2025-24976 is a known-severity vulnerability. It was published on February 11, 2025.
Technical description
Distribution is a toolkit to pack, ship, store, and deliver container content. Systems running registry versions 3.0.0-beta.1 through 3.0.0-rc.2 with token authentication enabled may be vulnerable to an issue in which token authentication allows an attacker to inject an untrusted signing key in a JSON web token (JWT). The issue lies in how the JSON web key (JWK) verification is performed. When a JWT contains a JWK header without a certificate chain, the code only checks if the KeyID (`kid`) matches one of the trusted keys, but doesn't verify that the actual key material matches. A fix for the issue is available at commit 5ea9aa028db65ca5665f6af2c20ecf9dc34e5fcd and expected to be a part of version 3.0.0-rc.3. There is no way to work around this issue without patching if the system requires token authentication.

How can CyberStrike help with CVE-2025-24976?
CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2025-24976 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
