CWE-125

Description

When the HTTP stream wrapper follows a redirect and the response carries a Location header with an empty value, the redirect code reads one byte past the end of the heap buffer holding the location. The value of that out-of-bounds byte decides which redirect target is built, so a malicious server controls whether the client is sent to the host root or to the current directory.

Affected configurations

• php php (>= 8.2.0 < 8.2.34) • php php (>= 8.3.0 < 8.3.35) • php php (>= 8.4.0 < 8.4.26) • php php (>= 8.5.0 < 8.5.11)
