# Vulnerability: Multiple High-Risk Security Flaws Patched in Tor Browser 15.0.1
## CVE Details
- CVE ID: Not Specified (Multiple vulnerabilities patched; upstream Firefox/Mozilla advisories pending specific enumeration)
- CVSS Score: Not Specified (Described as "high-risk" and "high-impact")
- CWE: Not Specified
## Affected Systems
- Products: Tor Browser
- Versions: Prior to 15.0.1 (All supported OS builds: Windows, macOS, Linux, Android)
- Configurations: All configurations, as the update fixes base browser engine issues.
## Vulnerability Description
This security update addresses multiple high-impact security flaws affecting the Tor Browser. The majority of these fixes are inherited from security updates included in the latest **Firefox Extended Support Release (ESR)** and backported changes from **Firefox version 145**. Additionally, the **NoScript extension (updated to version 13.4)** includes several critical security patches to close potential script-based exploitation vectors. The core browser engine on desktop builds (Firefox 140.5.0esr) and Android builds (GeckoView) have been hardened.
## Exploitation
- Status: Unknown/Not explicitly stated (Implied that fixes address potential compromise before 15.0.1)
- Complexity: Not Specified
- Attack Vector: Likely a mix of Network, Adjacent, and Local, dependent on the underlying Firefox/NoScript vulnerabilities fixed.
## Impact
- Confidentiality: High (Potential compromise of user privacy, which is the core function of Tor Browser)
- Integrity: Moderate to High
- Availability: Low to Moderate (Dependent on vulnerability type)
## Remediation
### Patches
- **Tor Browser 15.0.1** is available for Windows, macOS, Linux, and Android.
- Desktop builds (Win/Mac/Linux) are based on **Firefox 140.5.0esr**.
- **NoScript extension** updated to **version 13.4**.
- **Android build** updated with a newer **GeckoView** engine.
### Workarounds
- None explicitly listed, as immediate updating is strongly recommended due to the "high-risk" nature of the issues.
## Detection
- Indicators of compromise would be specific to the underlying (but undisclosed) Firefox CVEs.
- Detection hinges on verifying the running version of Tor Browser across user endpoints.
