{"id":"CVE-2026-110263","summary":"OW2 ASM 3.0 before 9.11 Uncontrolled Recursion in SignatureReader","details":"OW2 ASM 3.0 before 9.11 contains an uncontrolled recursion vulnerability in SignatureReader.parseType() that allows attackers to exhaust the stack via deeply nested generic type signatures. Attackers can supply a crafted class file with a long Signature attribute containing many nested type arguments to trigger a StackOverflowError during class transformation, causing denial of service.","modified":"2026-10-15T02:47:47.478235844Z","published":"2026-10-14T14:16:34.949Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-674"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/110xxx/CVE-2026-110263.json"},"references":[{"type":"ADVISORY","url":"https://asm.ow2.io/versions.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/110xxx/CVE-2026-110263.json"},{"type":"PACKAGE","url":"https://gitlab.ow2.org/asm/asm"},{"type":"ARTICLE","url":"https://gitlab.ow2.org/asm/asm/-/blob/ASM_9_10_1/asm/src/main/java/org/objectweb/asm/signature/SignatureReader.java#L151"},{"type":"FIX","url":"https://gitlab.ow2.org/asm/asm/-/commit/8f87fc0317a4c5ee8f538bcbb641928def25dbd6"},{"type":"FIX","url":"https://gitlab.ow2.org/asm/asm/-/merge_requests/465"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-110263"},{"type":"WEB","url":"https://repo1.maven.org/maven2/"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/ow2-asm-3.0-before-9.11-uncontrolled-recursion-in-signaturereader"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://gitlab.ow2.org/asm/asm","events":[{"introduced":"27979790f50bb16044d19a68754931c9093071d0"},{"fixed":"baeba2ca4e5f8196795340b015ca8b69f39740f5"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"3.0"},{"fixed":"9.11"}]}}],"versions":["ASM_9_10_1","ASM_9_10","ASM_9_9_1","ASM_9_9","ASM_9_8","ASM_9_7_1","ASM_9_7","ASM_9_6","ASM_9_5","ASM_9_4","ASM_9_3","ASM_9_2","ASM_9_1","ASM_9_0","ASM_9_0_BETA","ASM_8_0_1","ASM_8_0","ASM_7_3_1","ASM_7_2","ASM_7_2_BETA","ASM_7_1","ASM_7_0","ASM_7_0_BETA","ASM_6_2_1","ASM_6_2","ASM_6_1_1","ASM_6_1","ASM_6_1_BETA2","ASM_6_1_BETA","ASM_6_0","ASM_6_0_BETA","ASM_5_2","ASM_5_1","ASM_5_0_4","ASM_5_0_3","ASM_5_0_2","ASM_5_0_1","ASM_5_0","ASM_5_0_BETA","ASM_4_2","ASM_4_1","ASM_4_0","ASM_4_0_RC2","ASM_4_0_RC1","ASM_3_3_2","ASM_3_3_1","ASM_3_3","ASM_3_1","ASM_3_0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-110263.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N"}]}
