CWE-683 vulnerabilities

CVE-2026-32269 is a medium severity vulnerability in parse-community's parse-server affecting versions prior to 9.6.0-alpha.13 and 8.6.39. The OAuth2 authentication adapter incorrectly validates app IDs when appidField and appIds are configured, sending malformed values to the token introspection endpoint instead of the user's actual access token. This flaw can cause OAuth2 logins to fail or, depending on the introspection endpoint's response, allow unauthorized authentication from disallowed app contexts. Exploitation does not require privileges or user interaction but has a high attack complexity. The vulnerability impacts deployments using the OAuth2 adapter with specific configurations and is fixed in the indicated patched versions.

malcontent discovers supply-chain compromises through.context, differential analysis, and YARA. Starting in version 1.8.0 and prior to version 1.20.3, malcontent could be made to create symlinks outside the intended extraction directory when scanning a specially crafted tar or deb archive. The `handleSymlink` function received arguments in the wrong order, causing the symlink target to be used as the symlink location. Additionally, symlink targets were not validated to ensure they resolved within the extraction directory. Version 1.20.3 introduces fixes that swap handleSymlink arguments, validate symlink location, and validate symlink targets that resolve within an extraction directory.
