Prior to version 2.6.0, `pontedilana/php-weasyprint` fetches the content of option values server-side via `file_get_contents()` when the value looks like a URL, without restricting the URL scheme. The `attachment` option of `Pdf` is the reachable sink: any value that passes `isOptionUrl()` (`filter_var(..., FILTER_VALIDATE_URL)`) is downloaded by the PHP process and embedded into the generated PDF. Because `FILTER_VALIDATE_URL` accepts `http`, `https`, `ftp`, `file` and PHP stream wrappers such as `php://`, an attacker who can influence the `attachment` value reaches both a **Server-Side Request Forgery** primitive (e.g. internal HTTP endpoints, cloud metadata) and a local file disclosure primitive (`file://`, `php://filter/...`), with the fetched bytes exfiltrated as a PDF attachment. This is the same class of issue KnpLabs/snappy patched for its `xsl-style-sheet` option in GHSA-c5fp-p67m-gq56. The library is documented as a one-to-one substitute for KnpLabs/snappy and shares the same code shape. PhpWeasyPrint version 2.6.0 contains a patch for the issue.","published_at":"2026-06-19T17:06:12.737000Z","last_modified_at":null,"cvss_v3_score":6.5,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","cvss_v3_severity":"MEDIUM","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-918"],"nvd_references":["https://github.com/pontedilana/php-weasyprint/security/advisories/GHSA-x8g9-h984-pc36","https://github.com/KnpLabs/snappy/security/advisories/GHSA-c5fp-p67m-gq56","https://github.com/pontedilana/php-weasyprint/commit/9582dcf119a405276cf55e9e10bc577a887792cb","https://github.com/pontedilana/php-weasyprint/releases/tag/2.6.0"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-28T23:30:45.962068Z"},"effective_severity":"MEDIUM","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"L","value_label":"Low"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"H","value_label":"High"},{"metric":"I","name":"Integrity","value":"N","value_label":"None"},{"metric":"A","name":"Availability","value":"N","value_label":"None"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"pontedilana","vendor_name":"pontedilana","product_slug":"php-weasyprint","product_name":"php-weasyprint","version_start":"< 2.6.0","version_start_inclusive":true,"version_end":"< 2.6.0","version_end_inclusive":true,"cpe23_uri":"cve5:pontedilana:php-weasyprint:< 2.6.0:< 2.6.0"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/pontedilana/php-weasyprint/security/advisories/GHSA-x8g9-h984-pc36","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/KnpLabs/snappy/security/advisories/GHSA-c5fp-p67m-gq56","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/pontedilana/php-weasyprint/commit/9582dcf119a405276cf55e9e10bc577a887792cb","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/pontedilana/php-weasyprint/releases/tag/2.6.0","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2026-06-19T17:06:12.737000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:55:10.688071Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:55:10.688071Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:55:10.688071Z","label":"CVSS score revised","source":"cvelistv5"}]}
