MEDIUMPre-NVD 5.95.9—
EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 5.9 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.8%, top 48% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

Anki is a program for creating and reviewing flashcards. Prior to 25.09.3, endpoints in Anki's local HTTP server do not adequately constrain requested media and built-in data paths, allowing scripts served from shared decks, or malicious websites combined with an origin-check bypass, to read local files through directory traversal. This issue is fixed in version 25.09.3.
