High (8.2) in dromara free-fs.
On this page
Dromara free-fs 2.0.1 through 2.3.1 contains an authorization bypass vulnerability that allows attackers to access code-protected shares because share codes are enforced only client-side. Attackers knowing a share ID can call the share items and download endpoints to list and download files without the code, even on preview-only shares.

Explain CVE-2026-129164 for an engineer deciding whether to act. Use https://cve.bz/api/public/cves/CVE-2026-129164?via=ask-ai-copy and https://cve.bz/cve/CVE-2026-129164?via=ask-ai-copy as the source of truth: what is affected and which versions fix it, whether it is in CISA KEV, public exploits, and its EPSS (an internet-wide 30-day estimate of exploitation activity, not a forecast for my systems). If they give no fixed versions, use the CVE record https://cveawg.mitre.org/api/cve/CVE-2026-129164 or the vendor advisory, not third-party mirrors. Tell me how to check whether I am affected and how to verify a fix. Cite the sources and say where they are uncertain.Opens a third-party assistant; its answer is its own, not cve.bz's. The prompt holds only this CVE's id and public links.
