CVE-2026-42393

The comparison used for the doveadm password and API key is not fully timing safe and can reveal the length of the configured secret. An attacker with access to the same network as the doveadm service, able to make repeated requests and measure response timing accurately, can learn the length of...

CVE-2026-59276

Several components in Spring Security compare security-sensitive values using standard string equality String.equals rather than a constant-time comparison. Because String.equals returns as soon as it finds a differing character, the time taken to reject an incorrect value is proportional to the...

Several components in Spring Security compare security-sensitive values using standard string equality String.equals rather than a constant-time comparison. Because String.equals returns as soon as it finds a differing character, the time taken to reject an incorrect value is proportional to the...

EUVD-2026-65214

The getgrav/grav-plugin-login Composer plugin before 3.9.1 used by Grav compares password reset and account activation tokens using a non-constant-time === string comparison instead of hashequals in classes/Controller.php taskReset and login.php activation handler. Because the token-submission...

CVE-2026-53525

A flaw was found in WeeChat, a free chat client. The relay authentication mechanism uses a non-constant-time comparison when verifying password hashes. This vulnerability allows a remote attacker to exploit subtle timing differences during the authentication process. By analyzing these timing...

Astra Linux – Vulnerability in mbedtls

A timing side channel in mbedtlsssldecryptbuf in library/sslmsg.c in Trusted Firmware Mbed TLS from version 2.23.0 allows an attacker to obtain secret key information. This issue affects the CBC mode, as it involves a calculated time difference based on the padding length...

Astra Linux – Vulnerability in gnutls28

A timing side-channel vulnerability in the handling of RSA ClientKeyExchange messages was discovered in GnuTLS. This side-channel can be used to recover the key encrypted in the RSA ciphertext across a network, in a Bleichenbacher-style attack. To successfully decrypt the data, the attacker would...

Astra Linux – Vulnerability in gnutls28

A vulnerability was discovered in GnuTLS. The response times to malformed ciphertexts in the RSA-PSK ClientKeyExchange differ from those of ciphertexts with correct PKCS1 v1.5 padding. This issue may allow a remote attacker to perform a timing side-channel attack during the RSA-PSK key exchange,...

Astra Linux – Vulnerability in mbedtls

A issue was discovered in Mbed TLS 2.x before 2.28.7, and in 3.x before 3.5.2. There was a timing-related side channel in RSA private operations. This side channel could allow a local attacker to recover the plaintext. It required the attacker to send a large number of messages for decryption, as...

Vulnerabilities of the functions tcp_inbound_md5_hash(), tcp_v4_send_reset(), and tcp_v6_send_reset() in the Linux operating system, allowing attackers to compromise the confidentiality, integrity, and accessibility of protected information

The vulnerabilities of the functions tcpinboundmd5hash, tcpv4sendreset, and tcpv6sendreset in the Linux operating system are related to the disclosure of information due to the observed difference in execution time. Exploiting these vulnerabilities can allow a remote attacker to compromise the...

CVE-2026-44255 Wazuh: Username Enumeration via Timing Side-Channel

Wazuh is a free and open source platform used for threat prevention, detection, and response. From 4.0.0 until 4.14.6 and 5.0.0-beta2, AuthenticationManager.checkuser in framework/wazuh/rbac/orm.py performs checkpasswordhash only when the supplied username exists. A nonexistent username returns...

CVE-2026-75589

Net::OAuth versions before 0.33 for Perl check HMAC-SHA1, HMAC-SHA256 and PLAINTEXT signatures with a non-constant-time comparison in verify. Each of the three compares the signature carried in the message against the locally computed one with the eq operator, which returns as soon as the two...

UBUNTU-CVE-2026-75589

Net::OAuth versions before 0.33 for Perl check HMAC-SHA1, HMAC-SHA256 and PLAINTEXT signatures with a non-constant-time comparison in verify. Each of the three compares the signature carried in the message against the locally computed one with the eq operator, which returns as soon as the two...

OSEC-2026-17 Timing leak in NIST elliptic curves scalar multiplication

The scalar multiplication includes pre-computed tables for speedup introduced in mirage-crypto-ec 0.11.3. The lookup algorithm for these tables performs secret-dependent reads instead of scanning the entire table. Solution Instead of using the index n - 1, where n is secret-dependent, use i - 1, ...

CVE-2026-59502

: Observable Discrepancy vulnerability in Priority Portal Generator addon to Priority ERP developed by Soft Solutions. This issue affects Portal Generator addon to Priority ERP developed by Soft Solutions: All versions without Priwall v3...

CVE-2026-16458

The CVE concerns Oberon microsystem AG’s ocrypto library, affected in all versions since 3.0.0 and before 4.0.1. The issue is a padding oracle/timing side-channel flaw in RSA PKCS#1 v1.5 decryption that enables an attacker with local access to recover plaintexts by measuring decryption timing. Th...

CVE-2026-16458 Timing side-channel in RSA PKCS#1 v1.5 decryption in ocrypto

Padding oracle attack vulnerability in Oberon microsystem AG’s ocrypto library in all versions since 3.0.0 and prior to 4.0.1 allows an attacker to recover plaintexts via timing measurements of RSA PKCS1 v1.5 decrypt operations...
