GHSA-6x7r-m64x-22r6

GHSA-6x7r-m64x-22r6 PUBLISHED CVSS 6.5 MEDIUM

Record from GitHub Advisory Database · Published May 14, 2022

PHP before 5.4.42, 5.5.x before 5.5.26, and 5.6.x before 5.6.10 does not ensure that pathnames lack %00 sequences, which might allow remote attackers to read or write to arbitrary files via crafted input to an application that calls (1) a DOMDocument save method or (2) the GD imagepsloadfont function, as demonstrated by a filename\0.html attack that bypasses an intended configuration in which client users may write to only .html files.
