Remote code execution in Mozilla Firefox versions prior to 149.0.2 stems from multiple memory safety bugs allowing unauthenticated network attackers to execute arbitrary code without user interaction. Mozilla confirmed memory corruption evidence across affected versions (Firefox 149.0.1 and Thunderbird 149.0.1), though Thunderbird patch status remains unconfirmed. CVSS 9.8 reflects maximum severity due to network-accessible attack vector with no complexity barriers. No public exploit identified at time of analysis, though the CWE-787 out-of-bounds write class has high weaponization potential once technical details emerge from linked Bugzilla entries.

Multiple memory corruption vulnerabilities in Mozilla Firefox (< 149.0.2) and Firefox ESR (< 140.9.1) enable unauthenticated remote code execution with critical CVSS 9.8 severity. These memory safety bugs-including CWE-787 out-of-bounds write issues-affect both standard and Extended Support Release channels, with Mozilla confirming evidence of memory corruption exploitable for arbitrary code execution. No active exploitation confirmed (not in CISA KEV) and no public exploit identified at time of analysis, though CVSS vector indicates network-accessible attack requiring no user interaction.

Buffer overflow in Firefox WebGPU implementation allows remote code execution when users interact with malicious web content. Affects all Firefox versions prior to 149.0.2. Network-based attack requires user interaction (visiting crafted webpage) but no authentication. CVSS 8.8 reflects high confidentiality, integrity, and availability impact. No public exploit identified at time of analysis, though Mozilla's rapid patch release suggests significant risk potential.

Integer overflow in Firefox and Firefox ESR text rendering engine allows remote attackers to achieve arbitrary code execution via specially crafted web content. Affects Firefox versions prior to 149.0.2 and Firefox ESR prior to 140.9.1. Attack requires user interaction (visiting malicious webpage) but no authentication. CVSS 8.8 (High severity). No public exploit identified at time of analysis, though the vulnerability class (integer overflow leading to buffer overflow) is well-understood and exploitable.

Remote code execution in Mozilla Firefox and Thunderbird via memory corruption vulnerabilities allows unauthenticated remote attackers to execute arbitrary code without user interaction. Affects Firefox <149.0.2, Firefox ESR <115.34.1, and Firefox ESR <140.9.1 across desktop platforms. With CVSS 9.8 (critical severity, network-accessible, no privileges required) and CWE-119 buffer overflow classification, this represents multiple memory safety bugs that Mozilla assessed could be exploited for arbitrary code execution. No public exploit identified at time of analysis; EPSS data not provided but critical browser vulnerabilities historically attract rapid exploitation interest.

XML injection in xmldom's CDATA serialization allows remote attackers to inject arbitrary markup into generated XML documents without authentication. The vulnerability affects both the legacy xmldom package and @xmldom/xmldom when applications embed untrusted input into CDATA sections. Attackers can break out of CDATA context by including the sequence ]]> in user-controlled strings, causing downstream XML consumers to parse injected elements as legitimate markup. Vendor-released patches are available in versions 0.8.12 and 0.9.9. EPSS data not provided; no confirmed active exploitation (CISA KEV status: not listed). Public proof-of-concept code exists in the GitHub security advisory.

Stored XSS in File Browser's EPUB preview function (versions ≤v2.62.1) allows authenticated attackers to steal JWT tokens and escalate privileges by uploading malicious EPUB files. The vulnerability arises from passing allowScriptedContent:true to the epub.js library combined with an ineffective iframe sandbox (allow-scripts + allow-same-origin), enabling JavaScript in crafted EPUBs to access parent frame localStorage. CVSS 7.6 (AV:N/AC:L/PR:L/UI:R/S:C). No public exploit identified at time of analysis beyond the detailed PoC in the advisory. EPSS data not available. Vendor-released patch available per GitHub advisory. Low-privilege users with file upload permissions can weaponize this to compromise administrator sessions.

Prototype pollution in convict npm package version 6.2.4 allows attackers to bypass previous security fixes and pollute Object.prototype through crafted input that manipulates String.prototype.startsWith. The vulnerability affects applications processing untrusted input via convict.set() and can lead to authentication bypass, denial of service, or remote code execution if polluted properties reach dangerous sinks like eval or child_process. A working proof-of-concept exploit demonstrating the bypass technique exists in the advisory.

Prototype pollution in Mozilla's node-convict configuration library allows attackers to inject properties into Object.prototype via two unguarded code paths: config.load()/loadFile() methods that fail to filter forbidden keys during recursive merge operations, and schema initialization accepting constructor.prototype.* keys during default-value propagation. Applications using node-convict (pkg:npm/convict) that process untrusted configuration data face impacts ranging from authentication bypass to remote code execution depending on how polluted properties propagate through the application. This represents an incomplete fix for prior prototype pollution issues (GHSA-44fc-8fm5-q62h), with no public exploit identified at time of analysis.
