| CVE-2023-20540 | 2026-06-26 | N/A | N/A | ||
| An observable timing discrepancy in the ASP could allow a privileged attacker to perform a brute-force attack against the hash message authentication code, allowing arbitrary message input, potentially leading to a loss of data integrity. | |||||
| CVE-2026-6291 | 1 Wolfssl | 1 Wolfssl | 2026-06-26 | N/A | 6.5 MEDIUM |
| Bleichenbacher padding oracle in PKCS#7 KTRI decryption. When decrypting PKCS#7 EnvelopedData using RSA PKCS#1 v1.5 key transport, wolfSSL returned distinguishable error codes depending on whether RSA padding validation failed versus whether the decrypted content was malformed. An attacker able to submit crafted EnvelopedData messages and observe error responses could use this as a padding oracle to incrementally recover the encrypted Content Encryption Key (CEK). The fix generates a deterministic pseudo-random fake CEK on padding failure (via HMAC-SHA256) and proceeds with decryption identically, using constant-time operations throughout, so that all failure paths produce the same error regardless of padding validity. | |||||
| CVE-2026-47380 | 2026-06-25 | N/A | N/A | ||
| NocoDB is software for building databases as spreadsheets. Prior to 2026.04.1, sign-in response timing differed between known and unknown email addresses because the unknown-user branch returned without performing a password hash comparison. This vulnerability is fixed in 2026.04.1. | |||||
| CVE-2026-48166 | 2026-06-23 | N/A | 5.3 MEDIUM | ||
| Filament is a collection of full-stack components for accelerated Laravel development. From 4.0.0 until 4.11.5 and 5.6.5, the login page has an observable timing discrepancy that allows unauthenticated attackers to enumerate registered email addresses. The impact is limited to disclosing whether an account exists for a given email. This vulnerability is fixed in 4.11.5 and 5.6.5. | |||||
| CVE-2026-5091 | 2026-06-17 | N/A | 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-2026-5086 | 1 Nerdvana | 1 Crypt\ | 2026-06-17 | N/A | 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-2026-54411 | 2026-06-17 | N/A | 5.9 MEDIUM | ||
| Linux-PAM through 1.7.2 contains an observable timing discrepancy (CWE-208) in the pam_userdb module's plaintext-password comparison path in modules/pam_userdb/pam_userdb.c that allows a local or network-adjacent attacker able to repeatedly drive authentication through a calling service to recover the plaintext password of a target account by measuring response-timing differences. The comparison uses strncmp() (or strncasecmp() when PAM_ICASE_ARG is set) preceded by a length-equality check, so the time to reject a candidate depends on the index of the first differing byte and on whether the candidate's length matches the stored password, leaking the password length and individual prefix bytes. The vulnerable path is reached when the administrator configures pam_userdb with crypt=none, with an unrecognized crypt method, or without a crypt= argument, causing the module to store and compare credentials in plaintext. | |||||
| CVE-2026-48859 | 1 Erlang | 2 Erlang\/otp, Erlang\/ssh | 2026-06-17 | N/A | 5.3 MEDIUM |
| Observable Timing Discrepancy vulnerability in Erlang/OTP ssh (ssh_auth, ssh_options modules) allows unauthenticated remote username enumeration via timing side-channel in password authentication. When the SSH daemon is configured with the user_passwords or password option, ssh_auth:check_password/3 performs a PBKDF2-SHA256 computation with 600,000 iterations (~300ms) for valid usernames, but returns immediately (~0ms) for invalid usernames via the ssh_options:get_password_option/2 path. This timing difference is detectable in a single authentication attempt and allows an unauthenticated attacker to distinguish valid from invalid usernames. The user_passwords and password options are documented as intended for test purposes; the recommended alternative is pwdfun, which is not affected by this vulnerability. This vulnerability is associated with program files lib/ssh/src/ssh_auth.erl and lib/ssh/src/ssh_options.erl. This issue affects OTP from OTP 29.0 before 29.0.2 corresponding to ssh from 6.0 before 6.0.1. | |||||
| CVE-2026-48011 | 2026-06-17 | N/A | 3.7 LOW | ||
| Shopware is an open commerce platform. Prior to versions 6.6.10.18 and 6.7.10.1, an attacker is able to enumerate the usernames of administrator users by performing a timing attack. Versions 6.6.10.18 and 6.7.10.1 fix the issue. | |||||
| CVE-2026-47784 | 1 Memcached | 1 Memcached | 2026-06-17 | N/A | 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-2026-47373 | 2026-06-17 | N/A | 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-2026-44368 | 2026-06-17 | N/A | 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 | 2026-06-17 | N/A | 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 | 2026-06-17 | N/A | 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 | 2026-06-17 | N/A | 9.0 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-2026-41418 | 2026-06-17 | N/A | 5.3 MEDIUM | ||
| 4ga Boards is a boards system for realtime project management. Prior to 3.3.5, 4ga Boards is vulnerable to user enumeration via a timing side-channel in the login endpoint (POST /api/access-tokens). When an invalid username/email is provided, the server responds immediately (~17ms average). When a valid username/email is provided with an incorrect password, the server first performs a bcrypt.compareSync() operation (~74ms average) before responding. This ~4.4× timing difference is trivially detectable even over a network — a single request suffices. This vulnerability is fixed in 3.3.5. | |||||
| CVE-2026-41407 | 1 Openclaw | 1 Openclaw | 2026-06-17 | N/A | 3.7 LOW |
| OpenClaw before 2026.4.2 contains a timing side channel vulnerability in shared-secret comparison call sites that use early length-mismatch checks instead of fixed-length comparison helpers. Attackers can measure timing differences to leak secret-length information, weakening constant-time handling for shared secrets. | |||||
| CVE-2026-41263 | 1 Traefik | 1 Traefik | 2026-06-17 | N/A | 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-2026-41244 | 2026-06-17 | N/A | 4.7 MEDIUM | ||
| Mojic is a CLI tool to transform readable C code into an unrecognizable chaotic stream of emojis. Prior to 2.1.4, the CipherEngine uses a standard equality operator (!==) to verify the HMAC-SHA256 integrity seal during the decryption phase. This creates an Observable Timing Discrepancy (CWE-208), allowing a potential attacker to bypass the file integrity check via a timing attack. This vulnerability is fixed in 2.1.4. | |||||
| CVE-2026-41161 | 1 Sync-in | 1 Sync-in Server | 2026-06-17 | N/A | 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. | |||||
