{"id":"CVE-2026-25535","aliases":["GHSA-67pg-wm7f-q7fj"],"url":"https://o3.security/vulnerability/CVE-2026-25535","summary":"jsPDF Affected by Client-Side/Server-Side Denial of Service via Malicious GIF Dimensions","details":"### Impact\n\nUser control of the first argument of the `addImage` method results in denial of service.\n\nIf given the possibility to pass unsanitized image data or URLs to the `addImage` method, a user can provide a harmful GIF file that results in out of memory errors and denial of service. Harmful GIF files have large width and/or height entries in their headers, wich lead to excessive memory allocation.\n\nOther affected methods are: `html`.\n\nExample attack vector:\n\n```js\nimport { jsPDF } from \"jspdf\" \n\n// malicious GIF image data with large width/height headers\nconst payload = ...\n\nconst doc = new jsPDF();\n\ndoc.addImage(payload, \"GIF\", 0, 0, 100, 100);\n```\n\n### Patches\n\nThe vulnerability has been fixed in jsPDF 4.1.1. Upgrade to jspdf@>=4.2.0.\n\n### Workarounds\n\nSanitize image data or URLs before passing it to the addImage method or one of the other affected methods.\n### References\nhttps://github.com/ZeroXJacks/CVEs/blob/main/2026/CVE-2026-25535.md","published":"2026-02-19T14:34:05.648Z","modified":"2026-10-28T02:30:22.869476095Z","cvss":null,"epss":{"score":0.00717,"percentile":0.5217,"asOf":"2026-09-17"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"jspdf","fixedVersion":"4.2.0"}],"fix":{"url":"https://github.com/parallax/jsPDF/commit/2e5e156e284d92c7d134bce97e6418756941d5e6","label":"parallax/jsPDF@2e5e156"},"references":[{"type":"WEB","url":"https://github.com/ZeroXJacks/CVEs/blob/main/2026/CVE-2026-25535.md"},{"type":"WEB","url":"https://github.com/parallax/jsPDF/releases/tag/v4.2.0"},{"type":"WEB","url":"https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-25535.json"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:7110"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:7128"},{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2026-25535"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/25xxx/CVE-2026-25535.json"},{"type":"ADVISORY","url":"https://github.com/parallax/jsPDF/security/advisories/GHSA-67pg-wm7f-q7fj"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-25535"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2440992"},{"type":"FIX","url":"https://github.com/parallax/jsPDF/commit/2e5e156e284d92c7d134bce97e6418756941d5e6"},{"type":"PACKAGE","url":"https://github.com/parallax/jsPDF"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-28T02:30:22.869476095Z"}}
