CVE-2026-27856

CVE-2026-27856 concerns the doveadm credential verification path, where direct comparison enables a timing oracle to determine configured credentials. The issue affects the doveadm HTTP service component used by Open-Xchange-related deployments, enabling an attacker to infer credentials through t...

Open-Xchange OX Dovecot Pro 安全漏洞

Open-Xchange OX Dovecot Pro is a mail storage and delivery system provided by the German company Open-Xchange. Open-Xchange OX Dovecot Pro has a security vulnerability; this vulnerability stems from direct comparison in credential verification and makes it vulnerable to timing attack attacks, whi...

UBUNTU-CVE-2026-27856

Doveadm credentials are verified using direct comparison which is susceptible to timing oracle attack. An attacker can use this to determine the configured credentials. Figuring out the credential will lead into full access to the affected component. Limit access to the doveadm http service port,...

CVE-2026-29044 EVerest: Charging Continues When WithdrawAuthorization Is Processed Before TransactionStarted

EVerest is an EV charging software stack. Prior to version 2026.02.0, when WithdrawAuthorization is processed before the TransactionStarted event, AuthHandler determines transactionactive=false and only calls withdrawauthorizationcallback. This path ultimately calls Charger::deauthorize, but no...

CVE-2026-3580

In wolfSSL 5.8.4, constant-time masking logic in sp256getentry2569 is optimized into conditional branches bnez by GCC when targeting RISC-V RV32I with -O3. This transformation breaks the side-channel resistance of ECC scalar multiplication, potentially allowing a local attacker to recover secret...

CVE-2026-3579

wolfSSL 5.8.4 on RISC-V RV32I architectures lacks a constant-time software implementation for 64-bit multiplication. The compiler-inserted muldi3 subroutine executes in variable time based on operand values. This affects multiple SP math functions sp256mul9, sp256sqr9, etc., leading to a timing...

CVE-2026-32702

Cleanuparr is a tool for automating the cleanup of unwanted or blocked files in Sonarr, Radarr, and supported download clients like qBittorrent. From 2.7.0 to 2.8.0, the /api/auth/login endpoint contains a logic flaw that allows unauthenticated remote attackers to enumerate valid usernames by...

CVE-2026-33429

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.54 and 9.6.0-alpha.43, an attacker can subscribe to LiveQuery with a watch parameter targeting a protected field. Although the protected field value is properly stripped...

Traefik < 2.11.41 / 3.x < 3.6.11 Multiple Vulnerabilities

The version of Traefik installed on the remote macOS host is prior to 2.11.41 or 3.x prior to 3.6.11. It is, therefore, affected by multiple vulnerabilities: - mTLS bypass through the TLS SNI pre-sniffing logic related to fragmented ClientHello packets. When a TLS ClientHello is fragmented across...

EVerest 安全漏洞

EVerest is an open-source firmware for electric vehicle charging stations developed by EVerest. Versions of EVerest prior to 2026.02.0 contained security vulnerabilities. These vulnerabilities stemmed from issues with the WithdrawAuthorization function processing events before TransactionStarted,...

CVE-2026-23364

A flaw was found in ksmbd, a Linux kernel module. This vulnerability stems from the use of a non-constant time memory comparison function when verifying Message Authentication Codes MACs. A remote attacker could exploit this timing difference to conduct a timing attack, potentially leading to the...

In the Linux kernel, the following vulnerability has been resolved: ksmbd: Compare MACs in constant time To prevent timing attacks, MAC comparisons need to be constant-time. Replace the memcmp with the correct function, cryptomemneq...

Observable Timing Discrepancy

Overview Affected versions of this package are vulnerable to Observable Timing Discrepancy due to the cryptohmac.cc module using memcmp, a non-constant-time comparison function to validate user-provided HMAC signatures, rather than the timing-safe equivalents used elsewhere in the codebase. An...
