pywebp versions before v0.3.0 bundled libwebp binaries in wheels that are vulnerable to CVE-2023-4863. The vulnerability was a heap buffer overflow which allowed a remote attacker to perform an out of bounds memory write.
The problem has been patched upstream in libwebp 1.3.2. pywebp was updated to bundle a patched version of libwebp in v0.3.0.
No known workarounds without upgrading.
