BIT-OPENBAO-2025-54999 OpenBao: Timing Side-Channel in Userpass Auth Method

OpenBao exists to provide a software solution to manage, store, and distribute sensitive data including secrets, certificates, and keys. In versions 0.1.0 through 2.3.1, when using OpenBao's userpass auth method, user enumeration was possible due to timing difference between non-existent users an...

GHSA-7RW5-9F7Q-XJ36 Open WebUI: Account enumeration via observable login timing discrepancy

Summary The /api/v1/auths/signin endpoint leaked whether an email address belonged to a registered account through a response-time side channel. Password verification ran bcrypt only when the email was found in the database; for a non-existent email the request returned early without hashing. The...

CVE-2026-15432

When verifying a mac with a ChunkedMacVerification object, Tink compares the resulting tag with non constant time comparison. This potentially allows an attacker to use timinig information as a side channel in order to get information how many bytes of a given tag match the correct tag. This in...

CVE-2026-15432

The CVE concerns Tink-Java and Tink-Android’s ChunkedMacVerification: during tag verification, the implementation uses a non-constant-time comparison, enabling a timing side-channel that could reveal how many bytes of a given tag match the correct tag. This is described as a potential pathway for...

CVE-2026-15432 Observable Timing Discrepancy in Tink-Java and Tink-Android ChunkedMacVerification

When verifying a mac with a ChunkedMacVerification object, Tink compares the resulting tag with non constant time comparison. This potentially allows an attacker to use timinig information as a side channel in order to get information how many bytes of a given tag match the correct tag. This in...

When verifying a mac with a ChunkedMacVerification object, Tink compares the resulting tag with non constant time comparison. This potentially allows an attacker to use timinig information as a side channel in order to get information how many bytes of a given tag match the correct tag. This in...

postgresql: PostgreSQL: Credential recovery via covert timing channel in MD5 password comparison

A flaw was found in PostgreSQL. This vulnerability, a covert timing channel, exists in the comparison of MD5-hashed passwords during authentication. A remote attacker could exploit this to recover user credentials, gaining unauthorized access to the database. This issue specifically impacts...

CVE-2026-42218

xrdp is an open source RDP server. Versions 0.10.6 and prior contain a timing side-channel vulnerability in the login interface. Due to a discrepancy in response processing times, a remote attacker can infer the existence of a username on the system, leading to unauthorized information disclosure...

CVE-2026-42218

CVE-2026-42218 affects xrdp, an open source RDP server. The issue is a timing side‑channel in the login interface of versions 0.10.6 and earlier that allows remote observers to infer whether a username exists, enabling information disclosure via username enumeration. The vulnerability is explicit...

EUVD-2026-45926

SurrealDB before 3.1.0 evaluates user-supplied WHERE clauses in SELECT statements and SET/MERGE/CONTENT/PATCH clauses in UPDATE, UPSERT, INSERT ON DUPLICATE KEY UPDATE, and RELATE update-variant statements against full record data before enforcing PERMISSIONS FOR SELECT WHERE restrictions. An...

CVE-2026-9537 Mojo::JWT versions before 1.02 for Perl verify HMAC signatures with a non-constant-time string comparison

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...

JLSEC-2026-761

iPerf3 before 3.17, when used with OpenSSL before 3.2.0 as a server with RSA authentication, allows a timing side channel in RSA decryption operations. This side channel could be sufficient for an attacker to recover credential plaintext. It requires the attacker to send a large number of message...

JLSEC-2026-681 The side-channel protected T-Table implementation in wolfSSL up to version 5.6.5 protects against a...

The side-channel protected T-Table implementation in wolfSSL up to version 5.6.5 protects against a side-channel attacker with cache-line resolution. In a controlled environment such as Intel SGX, an attacker can gain a per instruction sub-cache-line resolution allowing them to break the...

JLSEC-2026-682 Generating the ECDSA nonce k samples a random number r and then truncates this randomness with a...

Generating the ECDSA nonce k samples a random number r and then truncates this randomness with a modular reduction mod n where n is the order of the elliptic curve. Meaning k = r mod n. The division used during the reduction estimates a factor qe by dividing the upper two digits a digit having e....

JLSEC-2026-688 Multiple constant-time implementations in wolfSSL before version 5.8.4 may be transformed into...

Multiple constant-time implementations in wolfSSL before version 5.8.4 may be transformed into non-constant-time binary by LLVM optimizations, which can potentially result in observable timing discrepancies and lead to information disclosure through timing side-channel attacks...

PYSEC-2026-3028 pyquorum: Timing side‑channel in mul_mod

Impact The mulmod 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 valu...

Chromium: CVE-2026-13809 Side-channel information leakage in Safe Browsing

This CVE was assigned by Chrome. Microsoft Edge Chromium-based ingests Chromium, which addresses this vulnerability. Please see Google Chrome Releases for more information...

CVE-2026-12426 Members <= 3.2.22 - Unauthenticated Sensitive Information Disclosure via REST API Pagination Side Channel

The Members – Membership & User Role Editor Plugin plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.2.22 via the membersfilterprotectedpostsforrest. This makes it possible for unauthenticated attackers to extract determine the existence...

CVE-2026-54736 Phalcon: Non-constant-time HMAC verification in `Encryption\Crypt::decrypt` (timing side-channel)

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...

UBUNTU-CVE-2026-15041

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...
