Privilege escalation in Microsoft Graphics Component on Windows 11 25h2 and Windows Server 2019 exploits a use-after-free condition, enabling authenticated local attackers to gain elevated system privileges. The vulnerability requires moderate complexity to exploit and affects confidentiality, integrity, and availability of affected systems. No patch is currently available.
Service Workers in Mozilla Firefox and Thunderbird versions below 147 are vulnerable to remote denial-of-service attacks that require no user interaction or authentication. An unauthenticated attacker can crash affected applications over the network, and public exploit code exists for this vulnerability. Currently no patch is available for remediation.
cpp-httplib versions prior to 0.30.1 are vulnerable to denial of service attacks due to insufficient validation of decompressed HTTP request body sizes. An unauthenticated remote attacker can send a malicious gzip or brotli-compressed request that decompresses to an arbitrarily large payload in memory, exhausting server resources. Public exploit code exists for this vulnerability, and a patch is available in version 0.30.1 and later.
RustCrypto's SM2 elliptic curve implementation in versions 0.14.0-pre.0 and 0.14.0-rc.0 is vulnerable to denial-of-service through improper input validation in the decrypt() function, allowing remote attackers to crash affected applications by submitting malformed or undersized ciphertext that triggers unhandled panics. Public exploit code exists for this vulnerability, though a patch is available.
CryptoLib versions prior to 1.4.3 contain a heap buffer overflow in the KMC crypto service's Base64 decoder, where oversized input strings can write beyond allocated buffer boundaries when processing KMC JSON responses. An attacker with network access to the KMC service can trigger this vulnerability to crash the spacecraft-ground station communication process or potentially execute arbitrary code. Public exploit code exists for this vulnerability, and no patch is currently available.
Flagforge versions 2.3.2 and earlier suffer from a Regular Expression Denial of Service (ReDoS) vulnerability in the user profile API endpoint that accepts unvalidated usernames containing regex metacharacters, allowing unauthenticated remote attackers to trigger excessive CPU consumption and deny service to legitimate users. The MongoDB regex engine processes these malicious patterns inefficiently, making the platform unavailable without administrator intervention. No patch is currently available; users should implement WAF rules to filter regex metacharacters from username inputs as a temporary mitigation.
Llama.cpp server endpoints fail to validate the n_discard parameter from JSON input, allowing negative values that trigger out-of-bounds memory writes when the context buffer fills.

iccDEV ICC color profile processing library versions 2.3.1 and below contain an infinite loop in the CalcProfileID function that allows unauthenticated remote attackers to cause denial of service. Public exploit code exists for this vulnerability, and affected systems should upgrade to version 2.3.1.1 or later to remediate the issue.
Denial of service in Anthropic's Model Context Protocol (MCP) TypeScript SDK versions up to and including 1.25.1 allows remote attackers to hang the Node.js event loop by submitting a crafted URI to the UriTemplate matcher. The dynamically built regex for RFC 6570 exploded array patterns contains nested quantifiers that trigger catastrophic backtracking, pinning CPU and rendering the process unresponsive. Publicly available exploit code exists, though EPSS is very low (0.02%) and it is not listed in CISA KEV, so real-world exploitation currently appears theoretical rather than widespread.
