Prior to version 0.0.22, a Path Traversal vulnerability exists when using non-default configuration options `UPLOAD_DIR` and `UPLOAD_KEEP_FILENAME=True`. An attacker can write uploaded files to arbitrary locations on the filesystem by crafting a malicious filename. Users should upgrade to version 0.0.22 to receive a patch or, as a workaround, avoid using `UPLOAD_KEEP_FILENAME=True` in project configurations.\n\n## Affected\n\n- `python-multipart < 0.0.22`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `python-multipart 0.0.22`\n\n## Package advisory (CVE-2026-24486)\n\nAffected packages:\n\n- `python-multipart < 0.0.22`\n\nPatched in:\n\n- `python-multipart 0.0.22`\n\nSource: https://osv.dev/vulnerability/GHSA-wp53-j4wj-2cfg\n\n## Vendor advisories\n\n- **RHSA-2026:3461** · Red Hat · fixed in: Red Hat AI Inference Server 3.2 · released 2026-02-27 · [advisory](https://access.redhat.com/errata/RHSA-2026:3461)\n- **RHSA-2026:3462** · Red Hat · fixed in: Red Hat AI Inference Server 3.2 · released 2026-02-27 · [advisory](https://access.redhat.com/errata/RHSA-2026:3462)\n- **RHSA-2026:3960** · Red Hat · fixed in: Red Hat Ansible Automation Platform 2.6 · released 2026-03-06 · [advisory](https://access.redhat.com/errata/RHSA-2026:3960)\n- **RHSA-2026:10184** · Red Hat · fixed in: Red Hat OpenShift AI 2.25 · released 2026-04-23 · [advisory](https://access.redhat.com/errata/RHSA-2026:10184)\n- **RHSA-2026:42644** · Red Hat · fixed in: Red Hat OpenShift AI 2.25 · released 2026-07-21 · [advisory](https://access.redhat.com/errata/RHSA-2026:42644)\n- **RHSA-2026:3782** · Red Hat · fixed in: Red Hat OpenShift AI 2.25 · released 2026-03-04 · [advisory](https://access.redhat.com/errata/RHSA-2026:3782)\n- **RHSA-2026:19712** · Red Hat · fixed in: Red Hat OpenShift AI 3.3 · released 2026-05-20 · [advisory](https://access.redhat.com/errata/RHSA-2026:19712)\n- **RHSA-2026:3713** · Red Hat · fixed in: Red Hat OpenShift AI 3.3 · released 2026-03-04 · [advisory](https://access.redhat.com/errata/RHSA-2026:3713)\n- **RHSA-2026:44696** · Red Hat · fixed in: Red Hat Satellite 6.17 · released 2026-07-23 · [advisory](https://access.redhat.com/errata/RHSA-2026:44696)\n- **RHSA-2026:1504** · Red Hat · fixed in: Red Hat Satellite 6.18 · released 2026-01-28 · [advisory](https://access.redhat.com/errata/RHSA-2026:1504)\n- **RHSA-2026:51357** · Red Hat · fixed in: Red Hat Satellite 6.18 · released 2026-08-06 · [advisory](https://access.redhat.com/errata/RHSA-2026:51357)\n- **Red Hat VEX** · Important · affected: Lightspeed Core, OpenShift Lightspeed, Red Hat AI Inference Server, Red Hat Ansible Automation Platform 2, Red Hat Enterprise Linux AI (RHEL AI) 3, Red Hat OpenShift AI (RHOAI), … · no fix planned: Red Hat Ansible Automation Platform 2, Red Hat Enterprise Linux AI (RHEL AI) 3, Red Hat OpenShift AI (RHOAI), Lightspeed Core, … · updated 2026-09-15 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-24486.json)","depth":"midnight","depthScore":60,"depthScoreParts":{"impact":47.3,"likelihood":0.4,"exploitation":12,"ransomware":0},"changes":[]}
