CVE-2024-53273 | GHSL-2024-110: Reflected XSS in /register in habitica

Exp

Habitica is an open-source habit-building program. Versions prior to 5.28.5 are vulnerable to reflected cross-site scripting. The `register` function in `RegisterLoginReset.vue` contains a reflected XSS vulnerability due to an incorrect sanitization function. An attacker can specify a malicious `redirectTo` parameter to trigger the vulnerability, giving the attacker control of the victim’s account when a victim registers or logins with a specially crafted link. Version 5.28.5 contains a patch.

Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:R)
A real person has to do something—click, install, enable—otherwise it doesn’t land.
Scope (S:C)
Breaking this can reach past the original component and bite other resources—bigger blast radius.
Confidentiality (C:L)
Some sensitive info could get out, but not a total data dump.
Integrity (I:L)
Attackers could change some data, but it’s limited—not everything goes.
Availability (A:N)
Service keeps running; no real outage angle.
