| CVE-2026-54685 | 2026-07-21 | N/A | 5.3 MEDIUM | ||
| FileBrowser Quantum is a free, self-hosted, web-based file manager. Prior to version 1.3.2-beta, the `/api/auth/login` authentication endpoint does not execute in constant time. When a non-existent username is supplied, the server returns a `401`/`403` response almost immediately. When a valid username is provided, the server performs a bcrypt password comparison, causing a measurable delay in the response time. Version 1.3.2-beta patches the issue. | |||||
| CVE-2026-45410 | 2026-07-21 | N/A | 5.3 MEDIUM | ||
| TREK is a collaborative travel planner. Prior to 3.0.18, early return on missing user during login flow allowed an attacker to enumerate valid user accounts via response timing discrepancy. When an email address existed in the database, the backend performed a bcrypt password comparison before returning a 401 Unauthorized, adding ~370 ms of latency. When the email did not exist, the backend returned immediately (~10 ms). This ~14× timing difference could be detected without any difference in HTTP status codes or response bodies. This vulnerability is fixed in 3.0.18. | |||||
| CVE-2026-9537 | 2026-07-20 | N/A | 5.3 MEDIUM | ||
| Mojo::JWT versions before 1.02 for Perl verify HMAC signatures with a non-constant-time string comparison. The decode() method compares the supplied signature to the recomputed HMAC with Perl's eq operator, which stops at the first differing byte, so the comparison time varies with the number of matching leading bytes. A caller that decodes attacker supplied tokens leaks the expected signature through this timing variation, which can be aggregated over many requests to recover the signature and forge a token. | |||||
| CVE-2026-44061 | 2026-07-20 | N/A | 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-2026-6656 | 2026-07-20 | N/A | 7.5 HIGH | ||
| Crypt::Password versions through 0.28 for Perl are susceptible to timing attacks. The check_password method uses the built-in eq operator. This allows discrepancies in timing to be used to guess the underlying hash. | |||||
| CVE-2026-56764 | 2026-07-15 | N/A | 3.7 LOW | ||
| Hono before 4.11.10 contains a timing attack vulnerability in the basicAuth and bearerAuth middlewares due to non-constant-time string comparison in the timingSafeEqual function. Attackers can exploit early termination of string equality checks to infer valid credentials through precise timing measurements. | |||||
| CVE-2026-21840 | 2026-07-15 | N/A | 3.1 LOW | ||
| HCL BigFix Platform is affected by a user enumeration vulnerability which might allow an attacker, through careful system control and response time monitoring, to perform some level of user enumeration for the BigFix service. | |||||
| CVE-2026-5419 | 2026-07-15 | N/A | 3.7 LOW | ||
| A flaw was found in gnutls. The PKCS#7 padding check, performed during decryption, was not constant-time. This timing side-channel could allow a remote attacker to potentially leak sensitive information about the padding bytes through observable timing differences. This vulnerability is a form of information disclosure. | |||||
| CVE-2026-47783 | 1 Memcached | 1 Memcached | 2026-07-15 | N/A | 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-2026-27856 | 2 Dovecot, Open-xchange | 2 Dovecot, Dovecot | 2026-07-15 | N/A | 7.4 HIGH |
| 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, install fixed version. No publicly available exploits are known. | |||||
| CVE-2026-54736 | 2026-07-13 | N/A | N/A | ||
| Phalcon is a high-performance, full-stack PHP framework. Prior to 5.14.1, Phalcon\Encryption\Crypt::decrypt compares the attacker-supplied HMAC tag against the freshly computed HMAC using PHP/Zephir identity comparison, which lowers to a byte-wise comparison that returns early on the first differing byte. This observable timing discrepancy can allow an attacker to recover a valid tag byte-by-byte and attach it to a chosen IV and ciphertext so that decrypt() accepts tampered encrypted content as authentic. This issue is fixed in version 5.14.1. | |||||
| CVE-2026-59218 | 1 Openwebui | 1 Open Webui | 2026-07-10 | N/A | 5.3 MEDIUM |
| Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. Prior to 0.10.0, the /api/v1/auths/signin endpoint looked users up by email and only ran bcrypt password verification when a credential existed, making registered-account attempts measurably slower than missing-email attempts and allowing unauthenticated account enumeration. This issue is fixed in version 0.10.0. | |||||
| CVE-2026-15041 | 1 Redhat | 3 389 Directory Server, Directory Server, Enterprise Linux | 2026-07-09 | N/A | 3.7 LOW |
| A flaw was found in 389 Directory Server. The PBKDF2-SHA256 password verification function uses standard memcmp() for comparing password hashes instead of a constant-time comparison function. A remote attacker could potentially use timing measurements of LDAP bind attempts to infer partial hash information, though practical exploitation is extremely difficult due to PBKDF2 computational overhead. | |||||
| CVE-2026-41516 | 1 Trustedfirmware | 1 Op-tee | 2026-07-07 | N/A | 2.5 LOW |
| OP-TEE is a Trusted Execution Environment (TEE) designed as companion to a non-secure Linux kernel running on Arm; Cortex-A cores using the TrustZone technology. Starting in version 4.5.0 and prior to version 4.11.0, the RSA PKCS#1 v1.5 decryption implementation in the Hisilicon HPRE crypto driver uses non-constant-time `memcmp()` for label hash verification and has multiple distinguishable error paths. This creates a Bleichenbacher-style padding oracle that allows an attacker to recover RSA PKCS#1 v1.5 plaintext. Version 4.11.0 contains a patch. As a workaround, disable Hisilicon HPRE RSA driver with `CFG_HISILICON_ACC_V3=n`. | |||||
| CVE-2026-41515 | 1 Trustedfirmware | 1 Op-tee | 2026-07-07 | N/A | 2.5 LOW |
| OP-TEE is a Trusted Execution Environment (TEE) designed as companion to a non-secure Linux kernel running on Arm; Cortex-A cores using the TrustZone technology. Starting in version 3.9.0 and prior to version 4.11.0, the RSA-OAEP decryption implementation in the NXP CAAM crypto driver uses non-constant-time `memcmp()` for label hash verification and has multiple distinguishable error paths. This creates a Manger-style padding oracle that allows an attacker to recover RSA-OAEP plaintext with approximately 1000-2000 adaptive chosen ciphertext queries. Version 4.11.0 contains a patch. As a workaround, disable the NXP CAAM RSA driver with `CFG_CRYPTO_DRV_RSA=n`. | |||||
| CVE-2026-41514 | 1 Trustedfirmware | 1 Op-tee | 2026-07-07 | N/A | 2.5 LOW |
| OP-TEE is a Trusted Execution Environment (TEE) designed as companion to a non-secure Linux kernel running on Arm; Cortex-A cores using the TrustZone technology. Starting in version 4.5.0 and prior to version 4.11.0, the RSA-OAEP decryption implementation in the Hisilicon HPRE crypto driver uses non-constant-time `memcmp()` for label hash verification and has multiple distinguishable error paths. This creates a Manger-style padding oracle that allows an attacker to recover RSA-OAEP plaintext with approximately 1000-2000 adaptive chosen ciphertext queries. Only affects plat-d06 with `CFG_HISILICON_ACC_V3=y`, which seems to be disabled by default. Version 4.11.0 contains a patch. As a workaround, disable Hisilicon HPRE RSA driver with `CFG_HISILICON_ACC_V3=n`. | |||||
| CVE-2026-27882 | 2026-06-30 | N/A | 4.8 MEDIUM | ||
| Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. Prior to 4.0.0-beta.461, the GitLab webhook endpoint uses a non-constant-time string comparison operator (!==) to validate the webhook secret token. This implementation is vulnerable to timing attacks, which could allow an attacker to gradually discover the secret token by measuring response time differences. This vulnerability is fixed in 4.0.0-beta.461. | |||||
| CVE-2026-13758 | 2026-06-30 | N/A | 3.7 LOW | ||
| CryptX versions before 0.088_001 for Perl compare AEAD authentication tags in non-constant time in the streaming decrypt_done path. The decrypt_done($tag) form compares it against the computed tag with memNE (memcmp() != 0), which short-circuits on the first differing byte, so its run time depends on the number of matching leading bytes. This affects all five AEAD modes: GCM, CCM, ChaCha20Poly1305, EAX and OCB. The one-shot *_decrypt_verify helpers are unaffected; they verify the tag inside libtomcrypt with a constant-time comparison. The timing difference is a tag-verification oracle. An attacker who can submit many candidate tags for the same nonce, ciphertext and associated data while measuring the timing precisely enough may recover the expected tag byte by byte and forge a message that verifies. | |||||
| CVE-2023-20572 | 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 the input of an arbitrary message, potentially leading to a loss of data integrity. | |||||
