Description
This issue tracks two CWE-416 Use After Free (UAF) and one CWE-415 Double Free vulnerabilities in Goahead versions <= 6.0.0. These are caused by JST values not being nulled when freed during parsing of JST templates. If the ME_GOAHEAD_JAVASCRIPT flag is enabled, a remote attacker with the privileges to modify JavaScript template (JST) files could exploit this by providing malicious templates. This may lead to memory corruption, potentially causing a Denial of Service (DoS) or, in rare cases, code execution, though the latter is highly context-dependent.

Weaknesses
CWE · root cause- CWE-415Double FreeThe product calls free() twice on the same memory address.
- CWE-416Use After FreeThe product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
