    CVE-2026-41888 (GCVE-0-2026-41888)

    Vulnerability from cvelistv5 – Published: 2026-05-14 16:53 – Updated: 2026-05-14 18:38

    Title
    Distribution: Tag deletion bypasses `storage.delete.enabled` configuration
    Summary
    Distribution is a toolkit to pack, ship, store, and deliver container content. Prior to 3.1.1, tag deletion via the DELETE /v2/<name>/manifests/<tag> endpoint bypasses the storage.delete.enabled: false configuration, allowing any API client to remove tags from repositories even when the operator has explicitly disabled deletion. This vulnerability is fixed in 3.1.1.

    Title
    Distribution has stale blob access resurrection via repo-scoped redis descriptor cache invalidation
    Summary
    Distribution is a toolkit to pack, ship, store, and deliver container content. Prior to 3.1.0, distribution can restore read access in repo a after an explicit delete when storage.cache.blobdescriptor: redis and storage.delete.enabled: true are both enabled. The delete path clears the shared digest descriptor but leaves stale repo-scoped membership behind, so a later Stat or Get from repo b repopulates the shared descriptor and makes the deleted blob readable from repo a again. This vulnerability is fixed in 3.1.0.

    Title
    Distribution affected by pull-through cache credential exfiltration via www-authenticate bearer realm
    Summary
    Distribution is a toolkit to pack, ship, store, and deliver container content. Prior to 3.1.0, in pull-through cache mode, distribution discovers token auth endpoints by parsing WWW-Authenticate challenges returned by the configured upstream registry. The realm URL from a bearer challenge is used without validating that it matches the upstream registry host. As a result, an attacker-controlled upstream (or an attacker with MitM position to the upstream) can cause distribution to send the configured upstream credentials via basic auth to an attacker-controlled realm URL. This vulnerability is fixed in 3.1.0.

    Title
    Distribution's token authentication allows attacker to inject an untrusted signing key in a JWT
    Summary
    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.
