Php · Php · CVE-2026-14355
**Name of the Vulnerable Software and Affected Versions**
PHP versions 8.2.0 through 8.2.31
PHP versions 8.3.0 through 8.3.31
PHP versions 8.4.0 through 8.4.22
PHP versions 8.5.0 through 8.5.7
**Description**
The OpenSSL extension contains a buffer allocation flaw in the AES-WRAP-PAD algorithm implementation. The output buffer for the AES key-wrap-with-padding operation is sized based on the plaintext length but fails to account for RFC 5649 expansion. This can lead to writing beyond the allocated memory, which corrupts heap metadata and may cause the application to abort. This issue occurs within the `openssl encrypt()` function.
**Recommendations**
Update PHP version 8.2.x to 8.2.32
Update PHP version 8.3.x to 8.3.32
Update PHP version 8.4.x to 8.4.23
Update PHP version 8.5.x to 8.5.8
