Remote code execution in Mozilla Firefox 143 and Thunderbird 143 allows unauthenticated network attackers to execute arbitrary code via memory corruption. The vulnerability stems from a memory safety bug (CWE-119 buffer overflow) exploitable without user interaction. CVSS score of 9.8 reflects critical severity with network-based attack vector, low complexity, and no privileges required. Vendor-released patches are available in Firefox 144 and Thunderbird 144. No public exploit identified at time of analysis, though Mozilla's assessment indicates the memory corruption is presumed exploitable with sufficient effort.
Use-after-free memory corruption in Mozilla Thunderbird 143+ and Firefox allows remote code execution via malicious web extensions exploiting the native messaging API on Windows. CVSS 9.8 (critical) with network-based attack vector requiring no user interaction or authentication. Patched in Firefox 144 and Thunderbird 144. No public exploit identified at time of analysis, but CVSS metrics indicate high exploitability (AV:N/AC:L/PR:N/UI:N) with complete impact to confidentiality, integrity, and availability.
Information disclosure in Mozilla Firefox and Thunderbird allows unauthenticated remote attackers to extract privileged browser process memory via malicious IPC messages from a compromised web content process. Affects Firefox <144, Firefox ESR <115.29 and <140.4, and Thunderbird <144 and <140.4. CVSS 9.8 indicates network-exploitable with no auth required, though actual exploitation requires first compromising a web content process. Vendor-released patches available (Firefox 144, Firefox ESR 115.29/140.4, Thunderbird 144/140.4). No public exploit identified at time of analysis; EPSS data not provided.
Out-of-bounds memory corruption in Mozilla Firefox and Thunderbird allows unauthenticated remote attackers to achieve code execution via malicious WebGL texture operations. A compromised web content process can exploit manipulated WebGL textures to trigger out-of-bounds reads and writes in privileged browser processes, potentially leading to full system compromise. Affects Firefox <144, Firefox ESR <115.29 and <140.4, and Thunderbird <144 and <140.4. Vendor-released patches available across all affected product lines. CVSS 9.8 reflects network-accessible, no-authentication-required attack with high impact across confidentiality, integrity, and availability. No public exploit identified at time of analysis, though the specific Bugzilla reference (1989127) indicates detailed technical analysis exists.
Remote code execution in Mozilla Firefox (all versions prior to 144, ESR prior to 140.4) and Thunderbird (all versions prior to 144, ESR prior to 140.4) allows unauthenticated remote attackers to execute arbitrary code, disclose sensitive information, or cause denial of service through a use-after-free vulnerability in MediaTrackGraphImpl::GetInstance(). With a critical CVSS score of 9.8 and no authentication required, this memory corruption flaw represents a severe security risk. No public exploit identified at time of analysis, though EPSS data not available to assess exploitation probability.
Blind SQL injection in SFS Consulting's Winsure platform (all versions through the 21.08.2025 release) allows remote unauthenticated attackers to manipulate backend database queries via crafted input. The flaw carries a CVSS 9.8 rating reflecting network-reachable, low-complexity exploitation with no privileges or user interaction required, and no public exploit identified at time of analysis. The advisory was issued by Turkey's national CERT (USOM), suggesting regional relevance to Turkish insurance-sector deployments.
Firefox for Android leaks password-related screen content through the Android task switcher card carousel, exposing sensitive information to local attackers with physical or remote access to the device. Affects Firefox for Android versions prior to 144. No public exploit identified at time of analysis, but exploitation is trivial requiring only device access and standard OS features. CVSS 9.1 reflects the unauthenticated network attack vector, though real-world exploitation typically requires local device access, making the practical risk moderate for most threat models.
Authentication bypass in Claroty Secure Access (formerly SRA) versions 3.3.0 through 4.0.2 lets a remote attacker abuse a flawed OpenID Connect (OIDC) login flow to create unauthorized accounts or impersonate existing OIDC-federated users. Because Claroty Secure Access brokers privileged remote access into OT/ICS environments, successful impersonation can hand an attacker a legitimate user's (potentially administrative) session. No public exploit identified at time of analysis; not listed in CISA KEV.
