Prior to version 2.6.0, `pontedilana/php-weasyprint` guarded the output filename against the `phar://` stream wrapper with a case-sensitive blacklist. PHP stream wrappers are case-insensitive, so `PHAR://`, `Phar://`, etc. bypass the check and reach `fileExists()` (`file_exists()`) in `prepareOutput()`. On PHP 7 (which the library still supports — PHP 7.4+), this triggers deserialization of a crafted PHAR archive's metadata, leading to remote code execution. This is the patch-bypass of CVE-2023-28115. The same issue and fix were handled upstream in KnpLabs/snappy (GHSA-92rv-4j2h-8mjj). PhpWeasyPrint version 2.6.0 contains a patch for the issue.","published_at":"2026-06-19T17:03:58.118000Z","last_modified_at":null,"cvss_v3_score":8.1,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","cvss_v3_severity":"HIGH","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-502"],"nvd_references":["https://github.com/pontedilana/php-weasyprint/security/advisories/GHSA-2fmj-p74r-3wjm","https://github.com/KnpLabs/snappy/security/advisories/GHSA-92rv-4j2h-8mjj","https://github.com/pontedilana/php-weasyprint/commit/d1aa487722b5a3cab9b222b85fdb5608a5a550c3","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":"HIGH","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":"H","value_label":"High"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"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":"H","value_label":"High"},{"metric":"A","name":"Availability","value":"H","value_label":"High"}]},"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-2fmj-p74r-3wjm","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/KnpLabs/snappy/security/advisories/GHSA-92rv-4j2h-8mjj","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/pontedilana/php-weasyprint/commit/d1aa487722b5a3cab9b222b85fdb5608a5a550c3","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":"2026-06-19T17:03:58.118000Z","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"}]}
