CVE-2026-24486
Summary
A Path Traversal vulnerability exists when using non-default configuration options
UPLOAD_DIRandUPLOAD_KEEP_FILENAME=True. An attacker can write uploaded files to arbitrary locations on the filesystem by crafting a malicious filename.Details
When
UPLOAD_DIRis set andUPLOAD_KEEP_FILENAMEisTrue, the library constructs the file path usingos.path.join(file_dir, fname). Due to the behavior ofos.path.join(), if the filename begins with a/, all preceding path components are discarded:This allows an attacker to bypass the intended upload directory and write files to arbitrary paths.
Affected Configuration
Projects are only affected if all of the following are true:
UPLOAD_DIRis setUPLOAD_KEEP_FILENAMEis set to TrueMAX_MEMORY_FILE_SIZE(triggering a flush to disk)The default configuration is not vulnerable.
Impact
Arbitrary file write to attacker-controlled paths on the filesystem.
Mitigation
Upgrade to version 0.0.22, or avoid using
UPLOAD_KEEP_FILENAME=Truein project configurations.Python-Multipart has Arbitrary File Write via Non-Default Configuration
