Published: May 18, 2026· Updated: May 19, 2026
Official Description
SGLangs multimodal generation runtime is vulnerable to an unauthenticated path traversal vulnerability, allowing an attacker to write arbitrary files anywhere the server process has write access, by including ../ sequences in the upload filename when sent to specific endpoints.
Risk Analysis
This critical path traversal vulnerability in SGLangs multimodal generation runtime allows an unauthenticated attacker to write arbitrary files. By including '../' sequences in upload filenames, an attacker can write files to any location the server process has write access. With a CVSS score of 9.1, this is a serious concern.
No public exploit is currently known for this vulnerability. The flaw is remotely exploitable and requires no authentication.
Apply any available patches or updates for SGLangs version 0.5.10 to address this path traversal vulnerability. Implement strict validation of filenames and paths to prevent directory traversal.
Technical Analysis
CVE-2026-7302 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.1.
