The documentation.pages[].path field can be used to write generated documentation files outside the intended build/dev/docs/<package>/ output directory. The documentation.pages[].source field can be used to read files outside the project directory and embed their contents into generated documentation output.\n\nAn attacker who can convince a victim to run gleam docs build on an untrusted project, or with untrusted gleam.toml content, can cause local files readable by the victim to be included in generated documentation artifacts, and can cause generated documentation files to be written outside the intended docs output directory.\n\nThis issue affects Gleam from 1.16.0 until 1.17.0.","cvss_v4":{"vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N","score":4.6},"cvss_v3":null,"cwes":["CWE-22"],"references":["https://cna.erlef.org/cves/CVE-2026-32685.html","https://github.com/gleam-lang/gleam/commit/81570611906b6b0039c948037094d09a68700f3a","https://github.com/gleam-lang/gleam/commit/c9230cd3045de8fd8481dae3a4557c0146df1430","https://github.com/gleam-lang/gleam/security/advisories/GHSA-wjx8-7w8m-p4v7","https://osv.dev/vulnerability/EEF-CVE-2026-32685"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:37:48.043517290+00:00"},"epss":{"cve":"CVE-2026-32685","score":0.00229,"percentile":0.13555,"date":"2026-10-25"},"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).
