Affected by this issue is the function cleanCache of the file pages/api/cache.js of the component Authentication Guard. The manipulation of the argument token leads to missing authentication. The attack may be initiated remotely. Versions 4.1.0 - 4.9.5.2 allow unauthenticated exploitation due to missing method check. In versions 4.9.5.7 - 4.10.10 a guard present but only enforced when CACHE_REVALIDATION_TOKEN is set. Default deployments remain unprotected. The vendor was contacted early about this disclosure but did not respond in any way.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":41,"depthScoreParts":{"impact":29.2,"likelihood":0.1,"exploitation":12,"ransomware":0},"changes":[{"seq":211916,"id":"CVE-2026-101004","ts":1790601051943,"field":"exploit_available","old":"false","new":"true"}]}
