Vulnerabilities 2

  • High 8.1
    CVE-2026-17543 Public exploit

    SQL injection in ext-pgsql via E'...' backslash breakout

    Improper escaping of backslashes in attacker-provided parameters would allow for trivial SQL injection in PHP versions from 8.2.* before 8.2.33, from 8.3.* before 8.3.33, from 8.4.* before 8.4.24, and from 8.5.* before 8.5.9.

  • Medium 5.4

    Stack overflow in phar with circular symlinks

    Circular symbolic links in phar archives could lead to unbounded recursion, exhausting the C stack and crashing the PHP process, in PHP versions from 8.2.* before 8.2.33, from 8.3.* before 8.3.33, from 8.4.* before 8.4.24, and from 8.5.* before 8.5.9.
