CVE-2023-0361 5 Debian, Fedoraproject, Gnu and 2 more 7 Debian Linux, Fedora, Gnutls and 4 more 2026-10-14 N/A 7.4 HIGH
A timing side-channel in the handling of RSA ClientKeyExchange messages was discovered in GnuTLS. This side-channel can be sufficient to recover the key encrypted in the RSA ciphertext across a network in a Bleichenbacher style attack. To achieve a successful decryption the attacker would need to send a large amount of specially crafted messages to the vulnerable server. By recovering the secret from the ClientKeyExchange message, the attacker would be able to decrypt the application data exchanged over that connection.
CVE-2025-13912 2026-10-14 N/A N/A
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.
CVE-2025-13166 2026-10-14 N/A 3.7 LOW
The SMS OTP flow fails to adequately handle error messages, allowing an attacker to infer the existence of registered user accounts based on the responses received during the OTP initiation process. This weakness can be exploited by an attacker to discover valid usernames within the system. The impact is amplified for accounts that have not configured a mobile number, as the enumeration is specifically tied to this condition. The discovery of these usernames can facilitate subsequent brute force attacks, social engineering attempts, and information leakage, potentially leading to reputational damage, loss of customer trust, and regulatory non-compliance.
CVE-2026-106351 2 Apple, Google 2 Iphone Os, Chrome 2026-10-14 N/A 5.3 MEDIUM
Observable discrepancy in Safebrowsing in Google Chrome on on iOS prior to 155.0.8059.39 allowed a remote attacker who had compromised the renderer process to obtain sensitive information via a crafted HTML page. (Chromium security severity: Medium)
CVE-2026-110141 1 Google 1 Chrome 2026-10-14 N/A 3.1 LOW
Observable discrepancy in Media in Google Chrome prior to 155.0.8059.79 allowed a remote attacker to leak cross-origin data via a crafted HTML page. (Chromium security severity: High)
CVE-2022-4304 2 Openssl, Stormshield 4 Openssl, Endpoint Security, Sslvpn and 1 more 2026-10-14 N/A 5.9 MEDIUM
A timing based side channel exists in the OpenSSL RSA Decryption implementation which could be sufficient to recover a plaintext across a network in a Bleichenbacher style attack. To achieve a successful decryption an attacker would have to be able to send a very large number of trial messages for decryption. The vulnerability affects all RSA padding modes: PKCS#1 v1.5, RSA-OEAP and RSASVE. For example, in a TLS connection, RSA is commonly used by a client to send an encrypted pre-master secret to the server. An attacker that had observed a genuine connection between a client and a server could use this flaw to send trial messages to the server and record the time taken to process them. After a sufficiently large number of messages the attacker could recover the pre-master secret used for the original connection and thus be able to decrypt the application data sent over that connection.
CVE-2021-33560 4 Debian, Fedoraproject, Gnupg and 1 more 8 Debian Linux, Fedora, Libgcrypt and 5 more 2026-10-14 5.0 MEDIUM 7.5 HIGH
Libgcrypt before 1.8.8 and 1.9.x before 1.9.3 mishandles ElGamal encryption because it lacks exponent blinding to address a side-channel attack against mpi_powm, and the window size is not chosen appropriately. This, for example, affects use of ElGamal in OpenPGP.
CVE-2020-14145 2 Netapp, Openbsd 10 Active Iq Unified Manager, Aff A700s, Aff A700s Firmware and 7 more 2026-10-14 4.3 MEDIUM 5.9 MEDIUM
The client side in OpenSSH 5.7 through 8.4 has an Observable Discrepancy leading to an information leak in the algorithm negotiation. This allows man-in-the-middle attackers to target initial connection attempts (where no host key for the server has been cached by the client). NOTE: some reports state that 8.5 and 8.6 are also affected.
CVE-2019-13627 4 Canonical, Debian, Libgcrypt20 Project and 1 more 4 Ubuntu Linux, Debian Linux, Libgcrypt20 and 1 more 2026-10-14 2.6 LOW 6.3 MEDIUM
It was discovered that there was a ECDSA timing attack in the libgcrypt20 cryptographic library. Version affected: 1.8.4-5, 1.7.6-2+deb9u3, and 1.6.3-2+deb8u4. Versions fixed: 1.8.5-2 and 1.6.3-2+deb8u7.
CVE-2018-0495 5 Canonical, Debian, Gnupg and 2 more 8 Ubuntu Linux, Debian Linux, Libgcrypt and 5 more 2026-10-14 1.9 LOW 4.7 MEDIUM
Libgcrypt before 1.7.10 and 1.8.x before 1.8.3 allows a memory-cache side-channel attack on ECDSA signatures that can be mitigated through the use of blinding during the signing process in the _gcry_ecc_ecdsa_sign function in cipher/ecc-ecdsa.c, aka the Return Of the Hidden Number Problem or ROHNP. To discover an ECDSA key, the attacker needs access to either the local machine or a different virtual machine on the same physical host.
CVE-2025-65185 1 Entrinsik 1 Informer 2026-10-13 N/A 2.8 LOW
There is a username enumeration via local user login in Entrinsik Informer v5.10.1 which allows malicious users to enumerate users by entering an OTP code and new password then reviewing application responses.
CVE-2026-72699 2026-10-12 N/A 5.3 MEDIUM
The Grav Login plugin (getgrav/grav-plugin-login) before 3.9.1 is vulnerable to email address enumeration. The register() method in classes/Login.php throws a distinct exception (EMAIL_NOT_AVAILABLE) when a submitted email address already belongs to an existing account, while allowing registration to proceed otherwise. Because the registration endpoint has no rate limiting, an attacker can enumerate which email addresses have accounts on the site, one guess per request.
CVE-2026-106506 1 Linuxfoundation 2 Backstage, Backstage\/plugin-scaffolder-backend 2026-10-09 N/A 5.3 MEDIUM
Backstage is an open framework for building developer portals. Prior to 4.1.0, the @backstage/plugin-scaffolder-backend package is affected by improper input validation in scaffolder task list ordering. An authenticated Backstage user with permission to create and read relevant scaffolder tasks may be able to infer confidential task data under specific conditions. Successful exploitation requires retained task secrets, visibility of a target task, knowledge of the secret structure, and repeated requests. This issue is fixed in version 4.1.0.

CVE-2019-3739 2 Dell, Oracle 16 Bsafe Cert-j, Bsafe Crypto-j, Bsafe Ssl-j and 13 more 2026-10-08 4.3 MEDIUM 6.5 MEDIUM
RSA BSAFE Crypto-J versions prior to 6.2.5 are vulnerable to Information Exposure Through Timing Discrepancy vulnerabilities during ECDSA key generation. A malicious remote attacker could potentially exploit those vulnerabilities to recover ECDSA keys.
CVE-2019-1563 1 Openssl 1 Openssl 2026-10-08 4.3 MEDIUM 3.7 LOW
In situations where an attacker receives automated notification of the success or failure of a decryption attempt an attacker, after sending a very large number of messages to be decrypted, can recover a CMS/PKCS7 transported encryption key or decrypt any RSA encrypted message that was encrypted with the public RSA key, using a Bleichenbacher padding oracle attack. Applications are not affected if they use a certificate together with the private RSA key to the CMS_decrypt or PKCS7_decrypt functions to select the correct recipient info to decrypt. Fixed in OpenSSL 1.1.1d (Affected 1.1.1-1.1.1c). Fixed in OpenSSL 1.1.0l (Affected 1.1.0-1.1.0k). Fixed in OpenSSL 1.0.2t (Affected 1.0.2-1.0.2s).
CVE-2018-5407 7 Canonical, Debian, Nodejs and 4 more 20 Ubuntu Linux, Debian Linux, Node.js and 17 more 2026-10-08 1.9 LOW 4.7 MEDIUM
Simultaneous Multi-threading (SMT) in processors can enable local users to exploit software vulnerable to timing attacks via a side-channel timing attack on 'port contention'.
CVE-2016-0762 6 Apache, Canonical, Debian and 3 more 15 Tomcat, Ubuntu Linux, Debian Linux and 12 more 2026-10-08 4.3 MEDIUM 5.9 MEDIUM
The Realm implementations in Apache Tomcat versions 9.0.0.M1 to 9.0.0.M9, 8.5.0 to 8.5.4, 8.0.0.RC1 to 8.0.36, 7.0.0 to 7.0.70 and 6.0.0 to 6.0.45 did not process the supplied password if the supplied user name did not exist. This made a timing attack possible to determine valid user names. Note that the default configuration includes the LockOutRealm which makes exploitation of this vulnerability harder.
CVE-2021-35477 3 Debian, Fedoraproject, Linux 3 Debian Linux, Fedora, Linux Kernel 2026-10-08 2.1 LOW 5.5 MEDIUM
In the Linux kernel through 5.13.7, an unprivileged BPF program can obtain sensitive information from kernel memory via a Speculative Store Bypass side-channel attack because a certain preempting store operation does not necessarily occur before a store operation that has an attacker-controlled value.
