EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 7.5 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.4%, top 69% 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).

FreshRSS is a free, self-hostable RSS aggregator. Prior 1.28.0, a bug in the auth logic related to master authentication tokens, this restriction is bypassed. Usually only the default user's feed should be viewable if anonymous viewing is enabled, and feeds of other users should be private. This vulnerability is fixed in 1.28.0.
