{"id":"JLSEC-2026-89","details":"Poppler ia a library for rendering PDF files, and examining or modifying their structure. A use-after-free (write) vulnerability has been detected in versions Poppler prior to 25.10.0 within the StructTreeRoot class. The issue arises from the use of raw pointers to elements of a `std::vector`, which can lead to dangling pointers when the vector is resized. The vulnerability stems from the way that refToParentMap stores references to `std::vector` elements using raw pointers. These pointers may become invalid when the vector is resized. This vulnerability is a common security problem involving the use of raw pointers to `std::vectors`. Internally, `std::vector `stores its elements in a dynamically allocated array. When the array reaches its capacity and a new element is added, the vector reallocates a larger block of memory and moves all the existing elements to the new location. At this point if any pointers to elements are stored before a resize occurs, they become dangling pointers once the reallocation happens. Version 25.10.0 contains a patch for the issue.","modified":"2026-07-18T00:02:24.226684894Z","published":"2026-04-13T13:20:05.063Z","upstream":["CVE-2025-52885","EUVD-2025-33795"],"database_specific":{"license":"CC-BY-4.0","sources":[{"id":"CVE-2025-52885","imported":"2026-07-17T22:41:09.827Z","modified":"2026-06-17T09:37:12.863Z","published":"2025-10-10T23:15:36.397Z","url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2025-52885","html_url":"https://nvd.nist.gov/vuln/detail/CVE-2025-52885","database_specific":{"status":"Deferred"}},{"url":"https://euvdservices.enisa.europa.eu/api/enisaid?id=EUVD-2025-33795","html_url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2025-33795","id":"EUVD-2025-33795","imported":"2026-07-17T22:41:14.048Z","modified":"2025-11-04T21:11:41Z","published":"2025-10-10T22:11:20Z"}]},"references":[{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2025/10/13/2"},{"type":"WEB","url":"https://gitlab.freedesktop.org/poppler/poppler/-/merge_requests/1884"},{"type":"WEB","url":"https://gitlab.freedesktop.org/poppler/poppler/-/merge_requests/1884#note_3114334"},{"type":"WEB","url":"https://securitylab.github.com/advisories/GHSL-2025-042_poppler/"}],"affected":[{"package":{"name":"Poppler_jll","ecosystem":"Julia","purl":"pkg:julia/Poppler_jll?uuid=9c32591e-4766-534b-9725-b71a8799265b"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"25.10.0+0"}]}],"database_specific":{"source":"https://github.com/JuliaLang/SecurityAdvisories.jl/tree/generated/osv/2026/JLSEC-2026-89.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
