CVE-2023-22798: Prior to commit 51867e0d15a6d7f80d5b714fd0e9976b9c160bb0, https://github.com/brave/adblock-lists removed re...

Prior to commit 51867e0d15a6d7f80d5b714fd0e9976b9c160bb0, https://github.com/brave/adblock-lists removed redirect interceptors on some websites like Facebook in which the redirect interceptor may have been there for security purposes. This could potentially cause open redirects on these websites. Brave's redirect interceptor removal feature is known as "debouncing" and is intended to remove unnecessary redirects that track users across the web.

Security readout for executives and security teams

Plain-English summary

Brave adblock-lists' debouncing feature could remove redirect interceptors on some sites, including Facebook. Some interceptors may have existed to prevent open redirects, so removal could let a user be sent through a trusted site to another destination. The CVE is medium severity and requires user interaction.

Executive priority

Treat this as a moderate web trust and phishing-adjacent risk, not an emergency unless your environment depends heavily on Brave adblock-lists at scale. Prioritize verification and update tracking because the public record lacks complete product-version mapping.

Technical view

CVE-2023-22798 is a CWE-601 open redirect issue in Brave adblock-lists behavior before commit 51867e0d15a6d7f80d5b714fd0e9976b9c160bb0. The CVSS 3.1 score is 6.1: network reachable, low complexity, no privileges required, user interaction required, changed scope, low confidentiality and integrity impact.

Likely exposure

Exposure is likely limited to environments using Brave adblock-lists with the affected debouncing behavior before the referenced commit. The source bundle does not provide browser version mapping, deployment prevalence, or a complete affected-site list.

Exploitation context

The sources do not show CISA KEV listing or confirmed active exploitation. Practical abuse would require convincing a user to follow a crafted redirect path, and impact is bounded to low confidentiality and integrity according to the CVSS record.

Researcher notes

Evidence is narrow: the CVE description, CVSS vector, CWE-601 classification, and HackerOne reference identify the issue class and commit boundary. Do not assume broader Brave browser exposure without release notes or vendor mapping. KEV is false in the supplied bundle.

Mitigation direction

  • Check Brave guidance and the referenced commit for the corrected adblock-lists state.
  • Update Brave adblock-lists or dependent packages to a version including the fix.
  • Disable or constrain debouncing behavior if vendor guidance recommends it.
  • Monitor for vendor advisories that map the commit to released browser or list versions.

Validation and detection

  • Inventory systems or products consuming Brave adblock-lists.
  • Confirm the deployed list includes commit 51867e0d15a6d7f80d5b714fd0e9976b9c160bb0 or later.
  • Review debouncing rules affecting redirect interceptors on high-risk sites.
  • Validate that security redirect interceptors remain intact after updating.
