GHSA-hm6c-rc5h-32m9
A vulnerability in curl's cookie parsing logic allows a malicious HTTP server to set 'super cookies' that bypass the Public Suffix List check. This flaw enables an attacker-controlled origin to inject cookies that curl then scopes and sends to unrelated third-party domains, potentially leading to unintended cookie sharing across domains.
AI Analysis
Technical Summary
CVE-2026-8924 describes a flaw in curl's handling of cookies where the Public Suffix List check is bypassed. This allows a malicious HTTP server to create 'super cookies' that curl incorrectly scopes, causing cookies to be sent to unrelated third-party domains. This behavior can lead to privacy and security issues due to cross-domain cookie leakage. No patch or remediation information is currently available, and no known exploits in the wild have been reported.
Potential Impact
The vulnerability can cause curl to send cookies to domains that should not receive them, violating cookie isolation boundaries enforced by the Public Suffix List. This may result in privacy breaches or unintended data exposure between unrelated domains when curl is used to make HTTP requests.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, users should be cautious when using curl to interact with untrusted HTTP servers, especially in contexts where cookie isolation is critical.
