{"id":"CVE-2026-24040","summary":"jsPDF has a Shared State Race Condition in addJS Plugin","details":"jsPDF is a library to generate PDFs in JavaScript. Prior to 4.1.0, the addJS method in the jspdf Node.js build utilizes a shared module-scoped variable (text) to store JavaScript content. When used in a concurrent environment (e.g., a Node.js web server), this variable is shared across all requests. If multiple requests generate PDFs simultaneously, the JavaScript content intended for one user may be overwritten by a subsequent request before the document is generated. This results in Cross-User Data Leakage, where the PDF generated for User A contains the JavaScript payload (and any embedded sensitive data) intended for User B. Typically, this only affects server-side environments, although the same race conditions might occur if jsPDF runs client-side. The vulnerability has been fixed in jsPDF@4.1.0.","aliases":["GHSA-cjw8-79x6-5cj4"],"modified":"2026-04-10T05:39:18.574709Z","published":"2026-02-02T20:38:24.732Z","related":["CGA-x488-wcrq-cxm8"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/24xxx/CVE-2026-24040.json","cwe_ids":["CWE-362"],"cna_assigner":"GitHub_M"},"references":[{"type":"WEB","url":"https://github.com/parallax/jsPDF/releases/tag/v4.1.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/24xxx/CVE-2026-24040.json"},{"type":"ADVISORY","url":"https://github.com/parallax/jsPDF/security/advisories/GHSA-cjw8-79x6-5cj4"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-24040"},{"type":"FIX","url":"https://github.com/parallax/jsPDF/commit/2863e5c26afef211a545e8c174ab4d5fce3b8c0e"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/mrrio/jspdf","events":[{"introduced":"0"},{"fixed":"02273814bf0222eda02944f9a14128811f3b5a33"}],"database_specific":{"versions":[{"introduced":"0"},{"fixed":"4.1.0"}]}}],"versions":["1.1.135","1.3.4","v.1.4.0","v0.9.0","v1.0.106","v1.0.115","v1.0.116","v1.0.119","v1.0.138","v1.0.150","v1.0.178","v1.0.272","v1.2.60","v1.2.61","v1.3.0","v1.3.3","v1.3.4","v1.3.5","v1.4.0","v1.4.1","v1.5.0","v1.5.1","v1.5.2","v1.5.3","v2,1,0","v2.0.0","v2.1.1","v2.2.0","v2.3.0","v2.3.1","v2.4.0","v2.5.0","v2.5.1","v2.5.2","v3.0.0","v3.0.1","v3.0.2","v3.0.3","v3.0.4","v4.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-24040.json"}},{"ranges":[{"type":"GIT","repo":"https://github.com/parallax/jspdf","events":[{"introduced":"0"},{"fixed":"02273814bf0222eda02944f9a14128811f3b5a33"}]}],"versions":["1.1.135","1.3.4","v.1.4.0","v0.9.0","v1.0.106","v1.0.115","v1.0.116","v1.0.119","v1.0.138","v1.0.150","v1.0.178","v1.0.272","v1.2.60","v1.2.61","v1.3.0","v1.3.3","v1.3.4","v1.3.5","v1.4.0","v1.4.1","v1.5.0","v1.5.1","v1.5.2","v1.5.3","v2,1,0","v2.0.0","v2.1.1","v2.2.0","v2.3.0","v2.3.1","v2.4.0","v2.5.0","v2.5.1","v2.5.2","v3.0.0","v3.0.1","v3.0.2","v3.0.3","v3.0.4","v4.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-24040.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:L/VA:N/SC:N/SI:N/SA:N"}]}
