{"id":"CVE-2026-49358","aliases":["GHSA-5g9f-cwwg-4p8g"],"url":"https://o3.security/vulnerability/CVE-2026-49358","summary":"PhpWeasyPrint vulnerable to arbitrary file deletion at shutdown via public $temporaryFiles","details":"PhpWeasyPrint is a PHP library allowing PDF generation from a URL or an HTML page. Prior to version 2.6.0, `AbstractGenerator::$temporaryFiles` is a public array, and `removeTemporaryFiles()` — invoked from `__destruct()` and from a registered shutdown function — calls `unlink()` on every entry without verifying that the path is contained within the temporary folder. Any code holding a reference to a generator instance can push an arbitrary path into the array and have it deleted on script shutdown. This mirrors the KnpLabs/snappy issue GHSA-87qc-37cw-84h4. PhpWeasyPrint version 2.6.0 contains a patch for the issue.","published":"2026-06-19T14:52:05.368Z","modified":"2026-08-07T11:50:20.045966686Z","cvss":{"score":3,"severity":"LOW","vector":"CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:U/C:N/I:L/A:L"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"pontedilana/php-weasyprint","fixedVersion":"2.6.0"}],"fix":{"url":"https://github.com/pontedilana/php-weasyprint/commit/6d328ffd3bcb800c7c2e8a594b1bff0c099c9391","label":"pontedilana/php-weasyprint@6d328ff"},"references":[{"type":"WEB","url":"https://github.com/pontedilana/php-weasyprint/releases/tag/2.6.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/49xxx/CVE-2026-49358.json"},{"type":"ADVISORY","url":"https://github.com/KnpLabs/snappy/security/advisories/GHSA-87qc-37cw-84h4"},{"type":"ADVISORY","url":"https://github.com/pontedilana/php-weasyprint/security/advisories/GHSA-5g9f-cwwg-4p8g"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-49358"},{"type":"FIX","url":"https://github.com/pontedilana/php-weasyprint/commit/6d328ffd3bcb800c7c2e8a594b1bff0c099c9391"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:50:20.045966686Z"}}
