Technical Analysis
DeepPavlov versions 1.0 through 1.7.0 contain a path traversal vulnerability in the untar function of the Model Download Handler component. This vulnerability allows remote attackers to manipulate file paths during archive extraction, potentially leading to unauthorized file system access. The vulnerability was responsibly disclosed to the project, but no official fix or response has been issued as of the publication date.
Potential Impact
An attacker can remotely exploit this vulnerability to perform path traversal during the untar operation, which may allow unauthorized reading or overwriting of files on the affected system. This could lead to data compromise or disruption of service depending on the files accessed or modified.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since the project has not responded or released a fix, users should consider applying manual mitigations such as restricting permissions of the extraction directory or avoiding use of the vulnerable untar function until an official patch is available.
