{"id":"CVE-2026-7258","summary":"Out-of-bounds read in urldecode() on NetBSD","details":"In PHP versions 8.2.* before 8.2.31, 8.3.* before 8.3.31, 8.4.* before 8.4.21, and 8.5.* before 8.5.6, some functions, including urldecode(), pass signed char to ctype functions (like isxdigit()). On the systems with default signed char and optimized table-lookup ctype functions - such as NetBSD - this can lead to accessing array with negative offset, which can trigger a denial of service.","aliases":["BIT-libphp-2026-7258","BIT-php-2026-7258","BIT-php-min-2026-7258","GHSA-m8rr-4c36-8gq4"],"modified":"2026-06-05T13:59:14.726396217Z","published":"2026-05-10T04:28:14.520Z","related":["ALSA-2026:22142","ALSA-2026:22143","ALSA-2026:22305","ALSA-2026:23388","CGA-8j2g-9gmw-vx6x","SUSE-SU-2026:1957-1","SUSE-SU-2026:1958-1","SUSE-SU-2026:2037-1","SUSE-SU-2026:2091-1","SUSE-SU-2026:21612-1","openSUSE-SU-2026:10747-1","openSUSE-SU-2026:20745-1"],"database_specific":{"cwe_ids":["CWE-125"],"unresolved_ranges":[{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"8.2.*"},{"fixed":"8.2.31"},{"introduced":"8.3.*"},{"fixed":"8.3.31"},{"introduced":"8.4.*"},{"fixed":"8.4.21"},{"introduced":"8.5.*"},{"fixed":"8.5.6"}]},{"source":"DESCRIPTION","extracted_events":[{"fixed":"8.2.31"},{"fixed":"8.3.31"},{"fixed":"8.4.21"},{"fixed":"8.5.6"}]}],"cna_assigner":"php","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/7xxx/CVE-2026-7258.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/7xxx/CVE-2026-7258.json"},{"type":"ADVISORY","url":"https://github.com/php/php-src/security/advisories/GHSA-m8rr-4c36-8gq4"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-7258"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/php/php-src","events":[{"introduced":"70ee6c20ad97e02c2b8098aeea96fefbbc3ac5c2"},{"fixed":"482ca6c19c4d776c37bcdd5823edd524f4199cfa"}],"database_specific":{"source":"CPE_RANGE","cpe":"cpe:2.3:a:php:php:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"8.2.0"},{"fixed":"8.2.21"}]}}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-7258.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:L/U:Amber"}]}
