{"id":"CVE-2026-59943","summary":"Dompdf: Embedded SVG images can leak existence of files and directories within the filesystem","details":"Dompdf is an HTML to PDF converter for PHP. In versions 3.15 and prior, if a malicious actor can supply unrestricted content for rendering by Dompdf they can utilize the SVG rendering functionality to leak filesystem information when rendering PDF files using image references within a data-URI encoded SVG document. Using an \u003cimage\u003e element inside a data-URI embedded SVG, an attacker can attempt to embed other files via the href or xlink:href attributes. When processing a file that does not exist (e.g. file:///DOESNOTEXIST), dompdf behaves differently than it does when accessing a file or directory that actually exists on the filesystem. This issue has been fixed in version 3.16.","aliases":["GHSA-j8qw-6jw8-r297"],"modified":"2026-07-31T03:34:10.318633854Z","published":"2026-07-28T20:19:22.746Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/59xxx/CVE-2026-59943.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-209"]},"references":[{"type":"WEB","url":"https://github.com/dompdf/dompdf/releases/tag/v3.1.6"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/59xxx/CVE-2026-59943.json"},{"type":"ADVISORY","url":"https://github.com/dompdf/dompdf/security/advisories/GHSA-j8qw-6jw8-r297"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-59943"},{"type":"FIX","url":"https://github.com/dompdf/dompdf/commit/6a58996865db05d8fede748507e50ac4b8c5bfd0"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/dompdf/dompdf","events":[{"introduced":"0"},{"fixed":"6a58996865db05d8fede748507e50ac4b8c5bfd0"},{"fixed":"6d4b4eb8500f7a786da8868ba463a71b725a4005"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"3.1.6"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v3.1.5","v3.1.4","v3.1.3","v3.1.2","v3.1.1","v3.1.0","v3.0.2","v3.0.1","v3.0.0","v2.0.3","v2.0.2","v2.0.1","v2.0.0","v1.2.2","v1.2.1","v1.2.0","v1.1.1","v1.1.0","v1.0.2","v1.0.1","v1.0.0","v0.8.6","v0.8.5","v0.8.4","v0.8.3","v0.8.2","v0.8.1","v0.8.0","v0.7.0","v0.7.0-beta3","v0.6.2","v0.6.1","v0.6.0","v0.6.0-b3"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-59943.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
