{"id":"BIT-libphp-2025-1220","summary":"Null byte termination in hostnames","details":"In PHP versions:8.1.* before 8.1.33, 8.2.* before 8.2.29, 8.3.* before 8.3.23, 8.4.* before 8.4.10 some functions like fsockopen() lack validation that the hostname supplied does not contain null characters. This may lead to other functions like parse_url() treat the hostname in different way, thus opening way to security problems if the user code implements access checks before access using such functions.","aliases":["BIT-php-2025-1220","BIT-php-min-2025-1220","CVE-2025-1220"],"modified":"2025-11-06T13:25:46.476Z","published":"2025-08-11T13:54:42.636Z","database_specific":{"cpes":["cpe:2.3:a:php:php:*:*:*:*:*:*:*:*"],"severity":"Medium"},"references":[{"type":"WEB","url":"https://github.com/php/php-src/security/advisories/GHSA-3cr5-j632-f35r"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-1220"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2025/07/11/4"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/07/msg00017.html"}],"affected":[{"package":{"name":"libphp","ecosystem":"Bitnami","purl":"pkg:bitnami/libphp"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"8.1.33"},{"introduced":"8.2.0"},{"fixed":"8.2.29"},{"introduced":"8.3.0"},{"fixed":"8.3.23"},{"introduced":"8.4.0"},{"fixed":"8.4.10"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/libphp/BIT-libphp-2025-1220.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N"}]}],"schema_version":"1.7.3"}
