{"id":"BIT-libphp-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-php-2026-7258","BIT-php-min-2026-7258","CVE-2026-7258","GHSA-m8rr-4c36-8gq4"],"modified":"2026-09-10T16:01:22.995560385Z","published":"2026-05-12T08:50:25.509Z","database_specific":{"cpes":["cpe:2.3:a:php:php:*:*:*:*:*:*:*:*"],"severity":"High"},"references":[{"type":"ADVISORY","url":"https://github.com/php/php-src/security/advisories/GHSA-m8rr-4c36-8gq4"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-7258"}],"affected":[{"package":{"name":"libphp","ecosystem":"Bitnami","purl":"pkg:bitnami/libphp"},"ranges":[{"type":"SEMVER","events":[{"introduced":"8.2.0"},{"fixed":"8.2.31"},{"introduced":"8.3.0"},{"fixed":"8.3.31"},{"introduced":"8.4.0"},{"fixed":"8.4.21"},{"introduced":"8.5.0"},{"fixed":"8.5.6"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/libphp/BIT-libphp-2026-7258.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}],"schema_version":"1.9.0"}
