description

Link Whisper Free versions through 0.9.7 are affected by a reflected cross-site scripting flaw. An attacker may cause script execution in a victim's browser if the victim is induced to interact with a crafted request or link.

mitigation

Update Link Whisper Free when a vendor-fixed release is available; no fixed version is recorded in the advisory. Until then, reduce exposure by restricting access to the affected site and cautioning users not to follow untrusted links.
