AnalysisAIv1 – Jul 15, 2026

Zip-slip path traversal in File Browser 2.63.6–2.63.16 allows a low-privileged user with upload permission to plant a POSIX backslash-named file that the archive builder incorrectly normalizes into a directory traversal sequence, enabling arbitrary file write on any victim who downloads and extracts the generated archive. The root cause is the server-side conversion of \ to / in archive entry names, which manufactures paths like ../../evil.sh from the legal POSIX filename ..\..\evil.sh. No public exploit identified at time of analysis, and the vulnerability is not listed in CISA KEV; however, the attack chain is straightforward for any user with upload access.

DescriptionCVE.org

File Browser is a file managing interface for uploading, deleting, previewing, renaming, and editing files within a specified directory. From 2.63.6 to 2.63.16, File Browser's archive builder uses strings.ReplaceAll(nameInArchive, "\", "/"), which turns a POSIX filename such as ..\..\evil.sh into the archive entry ../../evil.sh, allowing a user with upload permission to plant a backslash-named file that escapes the extraction directory when another user downloads and extracts the generated zip or tar archive. This issue is fixed in version 2.63.17.

What every action level means

Emergency Immediate action required. Criteria: CRITICAL + in CISA KEV (actively exploited) without patch, OR CRITICAL + EPSS > 30% without patch, OR CRITICAL + active threat signals without patch.

Act Now Prioritize within 24-48h. Criteria: in KEV with patch available, OR CRITICAL + public POC, OR HIGH + EPSS > 10%, OR CRITICAL + active threat, OR any CRITICAL severity.

This Week Schedule remediation this week. Criteria: HIGH severity (CVSS 7.0-8.9). Patch within normal change window.

This Month Plan within 30 days. Criteria: MEDIUM severity (CVSS 4.0-6.9), lower exploitation probability. Include in regular patch cycle.

Monitor Track and reassess. Criteria: LOW severity (CVSS 0.1-3.9), minimal exploitation risk. No immediate action needed.
