CVE-2022-2860 is an insufficient policy enforcement vulnerability identified within the Cookies component of the Chromium browser core.
The flaw arises when the browser fails to correctly enforce security policies and boundary checks during cookie creation and validation processes.
When a user visits a malicious or specially crafted website, the browser may improperly handle cookie attributes.
This allows a remote attacker to bypass intended security controls and access sensitive information or session states.
The vulnerability operates at the browser level, bypassing standard SameSite or secure flag checks under specific conditions.
Attackers leverage this by constructing specific HTTP responses containing anomalous cookie headers.
The Chromium cookie parsing engine accepts these malformed or loosely validated rules due to logic gaps.
Consequently, restricted cookie data can be exposed to unintended domains or contexts without proper isolation.
Although classified as medium severity, it poses significant confidentiality risks in multi-tenant or shared environments.
The issue was discovered externally and reported to the Chromium project team via their bug tracking system.
Security researchers demonstrated how policy enforcement bypasses can lead to unauthorized information disclosure.
Google integrated fixes into the Chromium codebase by tightening validation checks within the cookie jar implementation.
The patch explicitly enforces strict adherence to cookie scope boundaries and origin restrictions.
Users running unpatched versions prior to the update are vulnerable to cross-site cookie manipulation attacks.
Organizations are strongly advised to update their browsers to the latest stable release to mitigate this risk.
The vulnerability underscores the importance of rigorous input validation and policy enforcement in web clients.
Browser-based security relies heavily on correct implementation of RFC standards for cookie management.
Any deviation in policy evaluation can open pathways for secondary exploitation chains by threat actors.
The fix required modifying core cookie storage modules to reject ambiguous attribute declarations.
Testing confirmed that the updated cookie manager successfully blocks unauthorized cross-origin accesses.
The associated GitHub repository tracks such advisory disclosures and patch metadata for automated analysis.
Security teams monitor these repositories to maintain up-to-date vulnerability management inventories.
Understanding the mechanics of cookie policy failures helps developers write safer web applications.
Modern web browsers continue to harden their cookie subsystems against increasingly sophisticated attacks.
Proper patching ensures that client-side security states remain robust against policy bypass vectors.
DailyCVE Form:
Platform: Google Chrome
Version: Prior 104.0.5112.102
Vulnerability: Cookie policy enforcement
Severity: Medium severity
date: August 17 2022
Prediction: August 18 2022
What Undercode Say:
Bash Commands and Codes:
python3 main.py --base_dir ./data --cve_file ./cves.json --nvd_threads 10 --outfile results.json
Exploit: (Educational Purposes!)
The exploit vector involves setting up a malicious HTTP server that responds with malformed Set-Cookie headers designed to bypass origin isolation checks in vulnerable browser instances, tricking the client into exposing session cookies across different domains.
Protection: from this CVE
Update Google Chrome to version 104.0.5112.102 or later across all Windows, macOS, and Linux endpoints to enforce proper cookie policy checks.
Impact:
Allows remote attackers to bypass security restrictions and gain unauthorized access to sensitive cookie information via crafted web pages.
