Prior to 26.4.0, transactional email templates in Papra interpolate user.name directly into HTML without escaping or sanitization. An attacker who registers with a display name containing HTML tags will have those tags injected into the verification and password reset email bodies. Since emails are sent from the legitimate domain (e.g: auth@mail.papra.app), this enables convincing phishing attacks that appear to originate from official Papra notifications. This vulnerability is fixed in 26.4.0."}], "lastModified": "2026-04-24T15:31:18.307", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:papra:papra:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "D2F10801-36E9-47AD-AD2D-DA4709B67B72", "versionEndExcluding": "26.4.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
