CVE-2026-5091 1 Jjnapiork 1 Catalyst::plugin::authentication 2026-05-22 5.1 Medium
Catalyst::Plugin::Authentication versions through 0.10024 for Perl is susceptible to timing attacks. These versions use Perl's built-in eq comparison. Discrepencies in timing could be used to guess the underlying hash or password.
CVE-2026-47373 1 Rrwo 1 Crypt::saltedhash 2026-05-21 7.5 High
Crypt::SaltedHash versions through 0.09 for Perl is susceptible to timing attacks. These versions use Perl's built-in eq comparison. Discrepencies in timing could be used to guess the underlying hash.
CVE-2026-44061 1 Netatalk 1 Netatalk 2026-05-21 5.9 Medium
Netatalk 1.5.0 through 4.4.2 uses DES-ECB for authentication with a timing side channel, which allows a remote attacker to recover authentication credentials via timing analysis.
CVE-2026-47784 1 Memcached 1 Memcached 2026-05-20 8.1 High
In memcached before 1.6.42, password data for SASL password database authentication has a timing side channel because memcmp is used by sasl_server_userdb_checkpass.
CVE-2026-47783 1 Memcached 1 Memcached 2026-05-20 8.1 High
In memcached before 1.6.42, username data for SASL password database authentication has a timing side channel because a loop exits as soon as a valid username is found by sasl_server_userdb_checkpass.
CVE-2026-44368 1 Svvqt 1 Pyquorum 2026-05-15 N/A
PyQuorum is a cryptographic library for secret sharing and key management. Prior to 0.2.1, the mul_mod function implements multiplication via a binary expansion loop whose execution time depends on the Hamming weight of the second operand (the exponent). An attacker who can measure the time of secret‑sharing operations (e.g., via a remote service) could progressively recover the values of shares, ultimately leading to secret reconstruction. This vulnerability is fixed in 0.2.1.
CVE-2026-43514 1 Apache 1 Tomcat 2026-05-14 3.7 Low
Observable Timing Discrepancy vulnerability when comparing AJP secret in Apache Tomcat. This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.21, from 10.1.0-M1 through 10.1.54, from 9.0.0.M1 through 9.0.117, from 8.5.0 through 8.5.100, from 7.0.0 through 7.0.109. Older unsupported versions may also be affected. Users are recommended to upgrade to version 11.0.22, 10.1.55 or 9.0.118 which fix the issue.
CVE-2026-42602 1 Opentelemetry 1 Opentelemetry Collector Contrib 2026-05-14 8.1 High
azureauthextension is the Azure Authenticator Extension. From 0.124.0 to 0.150.0, a server-side authentication bypass in azureauthextension allows any party who holds a single valid Azure access token for any scope the collector's configured identity can mint for to authenticate to any OpenTelemetry receiver that uses auth: azure_auth. The extension's Authenticate method does not validate incoming bearer tokens as JWTs. Instead, it calls its own configured credential to obtain an access token and compares the client's token to the result with string equality — and the scope for that server-side token request is taken from the client-supplied Host header. As a result, a token minted for any Azure resource the service principal has ever been issued a token for (ARM, Graph, Key Vault, Storage, etc.) will authenticate to the collector if the attacker picks a matching Host. Tokens are replayable for the full issued lifetime (commonly several hours for managed identity tokens).
CVE-2026-41588 1 Inducer 1 Relate 2026-05-12 9 Critical
RELATE is a web-based courseware package. Prior to commit 2f68e16, there is a timing attack vulnerability in course/auth.py — check_sign_in_key(). This issue has been patched via commit 2f68e16.
CVE-2026-41161 1 Sync-in 2 Server, Sync-in Server 2026-05-12 5.3 Medium
Sync-in Server is a secure, open-source platform for file storage, sharing, collaboration, and syncing. Prior to version 2.2.0, the /api/auth/login endpoint contains a logic flaw that allows unauthenticated remote attackers to enumerate valid usernames by measuring the application's response time. This issue has been patched in version 2.2.0.
CVE-2025-9231 1 Openssl 1 Openssl 2026-05-12 6.5 Medium
Issue summary: A timing side-channel which could potentially allow remote recovery of the private key exists in the SM2 algorithm implementation on 64 bit ARM platforms. Impact summary: A timing side-channel in SM2 signature computations on 64 bit ARM platforms could allow recovering the private key by an attacker.. While remote key recovery over a network was not attempted by the reporter, timing measurements revealed a timing signal which may allow such an attack. OpenSSL does not directly support certificates with SM2 keys in TLS, and so this CVE is not relevant in most TLS contexts. However, given that it is possible to add support for such certificates via a custom provider, coupled with the fact that in such a custom provider context the private key may be recoverable via remote timing measurements, we consider this to be a Moderate severity issue. The FIPS modules in 3.5, 3.4, 3.3, 3.2, 3.1 and 3.0 are not affected by this issue, as SM2 is not an approved algorithm.
CVE-2023-50781 2 M2crypto Project, Redhat 5 M2crypto, Enterprise Linux, Rhev Hypervisor and 2 more 2026-05-12 7.5 High
A flaw was found in m2crypto. This issue may allow a remote attacker to decrypt captured messages in TLS servers that use RSA key exchanges, which may lead to exposure of confidential or sensitive data.
CVE-2026-43384 1 Linux 1 Linux Kernel 2026-05-11 9.8 Critical
In the Linux kernel, the following vulnerability has been resolved: net/tcp-ao: Fix MAC comparison to be constant-time To prevent timing attacks, MACs need to be compared in constant time. Use the appropriate helper function for this.
CVE-2026-43383 1 Linux 1 Linux Kernel 2026-05-11 9.4 Critical
In the Linux kernel, the following vulnerability has been resolved: net/tcp-md5: Fix MAC comparison to be constant-time To prevent timing attacks, MACs need to be compared in constant time. Use the appropriate helper function for this.
CVE-2026-32935 1 Phpseclib 1 Phpseclib 2026-05-08 5.9 Medium
phpseclib is a PHP secure communications library. Projects using versions 0.1.1 through 1.0.26, 2.0.0 through 2.0.51, and 3.0.0 through 3.0.49 are vulnerable to a to padding oracle timing attack when using AES in CBC mode. This issue has been fixed in versions 1.0.27, 2.0.52 and 3.0.50.
CVE-2026-40194 1 Phpseclib 1 Phpseclib 2026-05-08 3.7 Low
phpseclib is a PHP secure communications library. Starting in 0.1.1 and prior to 3.0.51, 2.0.53, and 1.0.28, phpseclib\Net\SSH2::get_binary_packet() uses PHP's != operator to compare a received SSH packet HMAC against the locally computed HMAC. != on equal-length binary strings in PHP uses memcmp(), which short-circuits on the first differing byte. This is a real variable-time comparison (CWE-208), proven by scaling benchmarks. This vulnerability is fixed in 3.0.51, 2.0.53, and 1.0.28.
CVE-2026-5086 1 Nerdvana 2 Crypt::secretbuffer, Crypt\ 2026-05-06 7.5 High
Crypt::SecretBuffer versions before 0.019 for Perl is suseceptible to timing attacks. For example, if Crypt::SecretBuffer was used to store and compare plaintext passwords, then discrepencies in timing could be used to guess the secret password.
CVE-2026-33006 1 Apache 2 Apache Http Server, Http Server 2026-05-04 4.8 Medium
A timing attack against mod_auth_digest in Apache HTTP Server 2.4.66 allows a bypass of Digest authentication by a remote attacker. Users are recommended to upgrade to version 2.4.67, which fixes this issue.
CVE-2026-41263 1 Traefik 1 Traefik 2026-05-01 3.7 Low
Traefik is an HTTP reverse proxy and load balancer. Prior to versions 2.11.43, 3.6.14, and 3.7.0-rc.2, there is a timing side-channel vulnerability in Traefik's BasicAuth middleware that allows an attacker to enumerate valid usernames through response-time differences. The variable intended to hold a constant-time fallback secret always resolves to an empty string, causing the constant-time comparison to short-circuit in microseconds rather than performing a full bcrypt evaluation. This restores the original timing oracle and makes it possible to distinguish existing users from non-existing ones by measuring authentication response times. This issue has been patched in versions 2.11.43, 3.6.14, and 3.7.0-rc.2.
CVE-2026-40972 2 Spring, Vmware 2 Spring Boot, Spring Boot 2026-04-30 7.5 High
An attacker on the same network as the remote application may be able to utilize a timing attack to discover information about the remote secret. In extreme circumstances this could result in the attacker determining the secret and uploading changed classes, thereby achieving remote code execution in the remote application. Affected: Spring Boot 4.0.0–4.0.5 (fix 4.0.6), 3.5.0–3.5.13 (fix 3.5.14), 3.4.0–3.4.15 (fix 3.4.16), 3.3.0–3.3.18 (fix 3.3.19), 2.7.0–2.7.32 (fix 2.7.33); DevTools remote secret comparison. Versions that are no longer supported are also affected per vendor advisory.
