An upstream fix is merged but not yet released — mitigate (WAF / firewall / segmentation) until the release ships, then apply it.

CyberPanel 2.4.3, fixed in commit eca0c3c, contains an arbitrary file read vulnerability in the file manager component that allows authenticated attackers to read sensitive system files by uploading a crafted ZIP archive containing symbolic links. Attackers can exploit the application's failure to validate symlinks before extraction, causing symbolic links targeting arbitrary filesystem paths outside the user's home directory to persist on disk and be accessed through the web interface.

An upstream fix is merged but not yet in a tagged release. Restrict network exposure of the affected system or apply the vendor's mitigation within your standard update timelines until it ships, then apply the release.

Exploitation public PoC (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact partial (CISA Vulnrichment). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
