Denial of service in Mattermost's Boards (focalboard) plugin allows any authenticated user to crash the plugin process and disrupt Boards availability for all users on the instance by sending a single malformed WebSocket message. The root cause is absent input validation on the teamId field type in custom_focalboard_SUBSCRIBE_TEAM WebSocket commands, classified under CWE-704 (Incorrect Type Conversion). Affected versions span 11.7.x through 11.7.6, 10.11.x through 10.11.21, and 11.8.x through 11.8.3; no public exploit has been identified at time of analysis.
Authentication bypass in the User Profile Builder WordPress plugin (versions through 3.16.4) lets unauthenticated attackers log in as the site's Administrator (user ID 1) by submitting a registration with a 61-70 character username, resulting in full site takeover. The flaw is a PHP type-confusion bug where an error object is silently coerced to the integer 1, binding an autologin nonce to the admin account. Rated CVSS 9.8; no public exploit identified at time of analysis, though the fix commit publicly reveals the exact defective code path.
File ownership privilege confusion in rsync before 3.5.0 allows local attackers to cause transferred files to be assigned root (uid/gid 0) ownership by manipulating the name-converter subprocess into returning empty uid/gid lookup responses. The flaw stems from rsync misinterpreting an empty name-converter response as a valid resolution to uid/gid 0 rather than rejecting it as a lookup failure. No public exploit or CISA KEV listing has been identified at time of analysis; the vendor-released fix is rsync v3.5.0, designated a major security release.
Denial-of-service in russh's Curve25519 key exchange client path allows any malicious SSH server to crash a connecting russh client session deterministically and pre-authentication, before host key verification occurs. Affected are all russh client deployments running versions prior to 0.62.4. An attacker operating or controlling an SSH server can terminate the client's spawned session task with a single malformed KEX_ECDH_REPLY packet; a working proof-of-concept is included in the GHSA advisory. No public exploit identified at time of analysis for active exploitation, and CISA KEV listing is absent, but the attack is reliable, requires no authentication, and a POC is publicly available.
Credential forgery via type confusion in the TCG TPM 2.0 reference code (versions through v184) allows a local attacker holding high-privilege access to submit a falsified TPM key - such as an Attestation Key, DevID Key, or TLS authentication key - to a TPM-aware Certificate Authority and receive a legitimate credential for it. With that credential, the attacker can forge subsequent TPM 2.0 attestations, silently undermining the platform integrity guarantees that downstream security controls depend on, including measured boot verification, zero-trust device posture checks, and DevID-based network admission. No public exploit code has been identified at time of analysis, and this vulnerability is not listed in the CISA KEV catalog; the EPSS score of 0.22% at the 13th percentile is consistent with a targeted, post-compromise technique rather than a commodity attack.
Local privilege escalation in the Windows Notification component lets an already-authenticated low-privileged user elevate to higher privileges (SYSTEM) across a broad range of Windows 10, Windows 11, and Windows Server releases. The flaw stems from an incorrect type conversion/cast (CWE-704) and carries a CVSS 7.8 (AV:L/AC:L/PR:L/UI:N) with high confidentiality, integrity, and availability impact. Microsoft has released a patch; there is no public exploit identified at time of analysis and the CVE is not listed in CISA KEV.
Denial of service in node-tar prior to 7.5.18 allows unauthenticated network-reachable attackers to crash Node.js processes by submitting crafted tar archives containing all-digit PAX header path or linkpath values. The library incorrectly coerces these string values to JavaScript numbers in src/pax.ts, causing downstream path handling (normalizeWindowsPath(entry.path).split('/')) to throw an uncaught TypeError when it attempts to call a string method on a numeric value. No public exploit code has been identified at time of analysis, and this vulnerability is not listed in the CISA KEV catalog.
Denial of service in NI grpc-device 2.17.0 and earlier allows an authenticated remote attacker to crash or destabilize the gRPC server by sending a crafted BeginSidebandStream message containing an out-of-range enum value. The unchecked cast triggers undefined behavior in the server process, with no public exploit identified at time of analysis. The flaw is reported by the vendor and tracked under GHSA-prfr-q8h3-mqxv.
Denial of service in the Go golang.org/x/crypto/ssh package (versions prior to 0.52.0) allows remote unauthenticated attackers to crash SSH server processes by sending crafted AES-GCM encrypted packets. An incorrectly placed bytes-to-int cast in the AES-GCM packet decoder triggers a server-side panic when processing well-crafted inputs. No public exploit identified at time of analysis, and EPSS exploitation probability is very low at 0.02%.
Ledger Live with vulnerable versions of ledgerhq/hw-app-eth prior to 6.34.7 contains an integer parsing vulnerability that allows attackers to manipulate EIP-712 typed data messages by exploiting. Rated medium severity (CVSS 6.9), this vulnerability is remotely exploitable, no authentication required, low attack complexity.
