Parse Server's built-in OAuth2 auth adapter exports a singleton instance that is reused directly across all OAuth2 provider configurations. Under concurrent authentication requests for different OAuth2 providers, one provider's token validation may execute using another provider's configuration, potentially allowing a token that should be rejected by one provider to be accepted because it is validated against a different provider's policy. Deployments that configure multiple OAuth2 providers via the `oauth2: true` flag are affected. The fix ensures that a new adapter instance is created for each provider instead of reusing the singleton, so each provider's configuration is isolated. There is no known workaround. If only a single OAuth2 provider is configured, the race condition cannot occur. - GitHub security advisory: https://github.com/parse-community/parse-server/security/advisories/GHSA-2cjm-2gwv-m892 - Fix Parse Server 9: https://github.com/parse-community/parse-server/releases/tag/9.6.0-alpha.11 - Fix Parse Server 8: https://github.com/parse-community/parse-server/releases/tag/8.6.37

Workspace boundary enforcement currently has three related bypass risks. This issue tracks fixing all three in one pull request. - What happens: Path validation can miss dangling symlink components during traversal checks. - Why it matters: A symlink that is unresolved at validation time can later resolve to an external location. - Impact: Read and write operations may escape workspace boundaries. - Affected area: src/security/path.rs (check_symlink_escape). - What happens: The path is validated first, then used later for filesystem operations. - Why it matters: A concurrent filesystem change can swap path components after validation but before open/write. - Impact: Race-based workspace escape is possible. - Affected area: Filesystem and file-consuming tools that call validate_path_in_workspace before I/O. - What happens: A file inside workspace can be a hardlink to an inode outside the intended workspace trust boundary. - Why it matters: Prefix and symlink checks can pass while data access still mutates or reads external content. - Impact: Policy bypass for read/write operations. - Affected area: Any tool that reads or writes via validated paths. | ID | Risk | Severity | Likelihood | Impact | |---|---|---|---|---| | R1 | Dangling symlink component bypass | High | Medium | Workspace boundary escape for read/write | | R2 | Validate/use TOCTOU race | High | Medium | Race-based boundary escape during file I/O | | R3 | Hardlink alias bypass | Medium | Low-Medium | External inode read/write through in-workspace path | 1.
