Images uploaded with HedgeDoc version 1.9.1 and later have an enumerable filename after the upload, resulting in potential information leakage of uploaded documents. This is especially relevant for private notes and affects all upload backends, except Lutim and imgur. This issue is patched in version 1.9.3 by replacing the filename generation with UUIDv4. If you cannot upgrade to HedgeDoc 1.9.3, it is possible to block POST requests to `/uploadimage`, which will disable future uploads.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":5.3},"cwes":["CWE-434","CWE-200"],"references":["https://github.com/hedgedoc/hedgedoc/commit/9e2f9e21e904c4a319e84265da7ef03b0a8e343a","https://github.com/hedgedoc/hedgedoc/security/advisories/GHSA-q6vv-2q26-j7rx","https://github.com/node-formidable/formidable/issues/808","https://github.com/hedgedoc/hedgedoc/commit/9e2f9e21e904c4a319e84265da7ef03b0a8e343a","https://github.com/hedgedoc/hedgedoc/security/advisories/GHSA-q6vv-2q26-j7rx"],"products":["hedgedoc:hedgedoc"],"source":"nvd","synced_at":"2026-10-19T21:30:03.577988018+00:00"},"epss":{"cve":"CVE-2022-24837","score":0.01126,"percentile":0.66322,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
