{"id":"CVE-2026-113352","summary":"uTox through 0.18.1 Path Traversal via Auto-Accepted File Transfers","details":"uTox through 0.18.1 contains a path traversal vulnerability that allows Tox friends to write arbitrary files by sending absolute or ../ file names to victims with auto-accept enabled. Attackers can overwrite shell startup files or plant crafted .ftinfo resume records that ft_find_resumeable() loads, abusing FILE pointers to write /proc/self/mem and execute code.","modified":"2026-10-21T02:56:00.267165831Z","published":"2026-10-20T10:41:38.136Z","database_specific":{"cwe_ids":["CWE-22"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/113xxx/CVE-2026-113352.json","cna_assigner":"VulnCheck"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/113xxx/CVE-2026-113352.json"},{"type":"PACKAGE","url":"https://github.com/uTox/uTox"},{"type":"ARTICLE","url":"https://github.com/uTox/uTox/blob/4b014491560c884b556f082d4d34c5229228bbc5/src/file_transfers.c#L249-L290"},{"type":"ARTICLE","url":"https://github.com/uTox/uTox/blob/4b014491560c884b556f082d4d34c5229228bbc5/src/xlib/filesys.c#L191-L214"},{"type":"REPORT","url":"https://github.com/uTox/uTox/issues/1587"},{"type":"FIX","url":"https://github.com/uTox/uTox/pull/1602"},{"type":"FIX","url":"https://github.com/uTox/uTox/pull/1603"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-113352"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/utox-through-0.18.1-path-traversal-via-auto-accepted-file-transfers"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/utox/utox","events":[{"introduced":"0"},{"last_affected":"4b014491560c884b556f082d4d34c5229228bbc5"}],"database_specific":{"extracted_events":[{"range":[{"introduced":"0"},{"last_affected":"0.18.1"}],"source":"AFFECTED_FIELD","strategy":"StandardRange"}]}}],"versions":["v0.18.1","v0.18.0","v0.17.2","v0.17.1","v0.17.0","v0.16.1","v0.16.0","v0.13.1","v0.13.0","v0.11.1","v0.11.0","v0.9.1","v0.9.3","v0.9.0","v0.8.1","v0.8.0","v0.7.0","v0.6.0","v0.5.1","v0.4.5","v0.4.4develop","v0.4.2","v0.3.2","v0.2.s","v0.2.r","v0.2.q","v0.2.o","v0.2.n","v0.2.m","v0.2.l","v0.2.k"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-113352.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
