# CVE-2026-8924: trailing dot domain super cookie

## TL;DR
trailing dot domain super cookie

## Key Points
- cve / CVE-2026-8924 / CURL-CVE-2026-8924 / severity:Low / https://github.com/curl/curl / GIT

## Details
**Severity:** Low
**Advisory:** CURL-CVE-2026-8924 (CVE-2026-8924)

**Affected (your watchlist):**
- `GIT:https://github.com/curl/curl` curl-8_9_1 → no fixed version listed [mac]

**Details:**
A flaw in curl’s cookie parsing logic allows a malicious HTTP server to set
"super cookies" that bypass the Public Suffix List check. This enables an
attacker-controlled origin to inject cookies that curl subsequently scopes and
transmits to unrelated third-party domains.
