DescriptionCVE.org

Mitigation bypass in Firefox for Android. This vulnerability was fixed in Firefox 150.

AnalysisAI

A mitigation bypass in Firefox for Android allows remote attackers to achieve high-impact integrity violations without authentication or user interaction. Fixed in Firefox 150, this CWE-200 information disclosure flaw enables attackers to circumvent existing security controls via network-based vectors. Despite a CVSS base score of 7.5 (High), real-world exploitation risk appears limited: EPSS probability is only 0.02% (5th percentile), no public exploit code has been identified, and CISA SSVC framework rates it as non-exploited with partial technical impact, though automatable.

Technical ContextAI

This vulnerability affects Mozilla Firefox for Android (CPE: cpe:2.3:a:mozilla:firefox:*:*:*:*:*:*:*:*) in versions prior to 150. Classified as CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor), the flaw represents a mitigation bypass that undermines existing security controls designed to protect information confidentiality or integrity. The Android-specific nature suggests platform-dependent security mechanisms may be involved, such as Android's sandboxing, permission model, or inter-process communication controls. The CVSS vector indicates zero confidentiality impact (C:N) but high integrity impact (I:H), meaning the bypass allows modification or manipulation of data rather than direct information disclosure despite the CWE-200 classification. This apparent contradiction suggests the mitigation being bypassed likely protects data integrity rather than confidentiality.

RemediationAI

Update Firefox for Android to version 150 or later, as confirmed in Mozilla Security Advisory MFSA2026-30 (https://www.mozilla.org/security/advisories/mfsa2026-30/). Firefox for Android typically auto-updates through the Google Play Store; administrators managing enterprise Android deployments should verify version 150 deployment through mobile device management (MDM) solutions. If immediate patching is not feasible, consider temporary compensating controls: restrict Firefox for Android browser usage to trusted networks only via firewall or VPN policies, though this significantly impacts mobile usability; implement network-level web filtering to block known malicious domains that might exploit the bypass, though the attack vector remains broad; or temporarily substitute alternative Android browsers until patching is complete, accepting the operational disruption of browser migration. No specific workaround is documented in vendor advisories, making version upgrade the only complete remediation. Organizations not deploying Firefox for Android can deprioritize this CVE.
