CVE-2026-82645 1 Wwbn 1 Avideo 2026-08-31 8.6 High
AVideo (current commit e01e41ecc and earlier) exposes stream credentials through the plugin/Live/view/Live_restreams/getLiveKey.json.php endpoint. Supplying a 'token' request parameter waives both the Live::canRestream() access gate and the restream ownership check, causing the endpoint to return any restream's stream_key and stream_url (credentials for external platforms such as YouTube, Facebook, and Twitch) without authentication. The token is merely encryptString() of an integer id with no user binding, expiry, or authentication tag. Because encryption uses AES-256-CBC with a deterministic IV and no MAC, and because intval() accepts any string beginning with a digit, an unauthenticated attacker can forge valid tokens using the public encryption oracle in view/url2Embed.json.php, disclosing arbitrary users' stream credentials.
CVE-2026-12860 2 Bouncycastle, Legion Of The Bouncy Castle Inc. 4 Bc-java, Bouncy Castle For Java Lts, Bc-java and 1 more 2026-08-28 5.3 Medium
In Bouncy Castle for Java before 1.85, RSA PKCS#1 verification skips last two hash bytes in NULL-omitted path. This issue also affects Bouncy Castle for Java LTS before 2.73.12.
CVE-2026-48526 2 Jpadilla, Pyjwt Project 2 Pyjwt, Pyjwt 2026-08-28 7.4 High
PyJWT is a JSON Web Token implementation in Python. Prior to 2.13.0, when the verifier is decoding JSON Web Tokens, while supporting both asymmetric and HMAC algorithms, the library does not validate use of JSON Web Keys in HMAC algorithm, allowing attacker to use the issuer public key as the secret key for HMAC algorithm. This vulnerability is fixed in 2.13.0.
CVE-2026-54330 1 Ceph 1 Ceph 2026-08-28 8.1 High
Ceph is an open-source distributed storage platform providing object, block, and file storage. In versions prior to 20.2.4 and 19.2.6, the Ceph Object Gateway (RGW) SigV4 handler does not reject requests that carry x-amz-* headers absent from the signed header set, allowing anyone holding a presigned URL to attach arbitrary unsigned x-amz-* headers that RGW will honor. AWS S3 requires every x-amz-* header on a SigV4 request to be signed and rejects requests bearing additional unsigned headers, but RGW validates only the headers listed in X-Amz-SignedHeaders and ignores any extra ones, so they take effect without being covered by the signature. By adding such headers to a presigned PUT URL, an attacker can grant themselves more capabilities than the URL's signer intended and escalate their privileges. This issue is fixed in versions 20.2.4 and 19.2.6.
CVE-2026-59639 2 Bouncycastle, Legion Of The Bouncy Castle Inc. 6 Bc-java, Bcpkix-fips, Bouncy Castle For Java Lts and 3 more 2026-08-28 7.5 High
In Bouncy Castle for Java before 1.85, CMS verifySignatures returns true for SignedData with zero signers. This issue also affects Bouncy Castle for Java LTS before 2.73.12, and Bouncy Castle for Java FIPS (BC-FJA) before bcpkix-fips 1.0.12 (1.0.X series), 2.0.12 (2.0.X series) and 2.1.12 (2.1.X series).
CVE-2026-76581 2 Wordpress, Wpmudev 2 Wordpress, Wpmu Dev Dashboard 2026-08-28 9.8 Critical
The WPMU DEV Dashboard plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 5.0.1. This is due to inconsistent and ambiguous HMAC message construction between the unauthenticated `wdpsso_step1` and `wdpsso_step2` AJAX actions, where step 1 signs and discloses an unseparated concatenation of the token, state, redirect, and domain values, while step 2 verifies an unseparated concatenation that omits the domain field. This makes it possible for unauthenticated attackers, on sites connected to WPMU DEV with Hub SSO enabled and mapped to an administrator, to obtain a valid HMAC from step 1 and replay it to step 2 by moving the domain value into the redirect field, resulting in an authenticated administrator session.
CVE-2026-68745 1 Apache 1 Cloudstack 2026-08-27 8.1 High
Certificate validation failures in SAML authentication in Apache CloudStack 4.20.3.0 and 4.22.1.0 on all platforms allow a malicious agent to forge a SAML response to the management server. The agent will have to spoof the ip address of the IdP or get an url of its own choosing registered in the management server, after which it can allow logging on with forged signatures. Users are recommended to upgrade to versions 4.20.3.1 or 4.22.1.1 and above, which fix this issue.
CVE-2026-19505 1 Rdk 1 Rdk-b Webui 2026-08-27 9.8 Critical
Improper cryptographic signature verification in `jst_functions.c` in RDK-B WebUI `rdkb-2025q4-kirkstone.04.10.26` allows a remote attacker to bypass authentication and obtain administrative access via a forged JWT containing an invalid RSA signature.
CVE-2026-72889 1 Vurtdev 1 Net-oauth 2026-08-26 9.8 Critical
Net::OAuth versions before 0.33 for Perl allow the sender to choose the signature algorithm in verify. verify resolves the signature method class from the signature_method parameter of the incoming message. signature_method is required on every request, so the algorithm used to check a signature is chosen by whoever sent it, and nothing lets the verifying party pin the method instead. When a message names HMAC-SHA1 or HMAC-SHA256, the key is derived from consumer_secret and token_secret rather than from the key the provider deployed. A provider deployed on RSA-SHA1 holds only the consumer public key, and RFC 5849 does not use consumer_secret for that method, so the required parameter is filled with a placeholder. A client that names HMAC-SHA1 instead has its signature checked against that placeholder, so a guessable one is enough to forge requests for any consumer key and token.
CVE-2026-15265 1 Tenable 1 Nessus Agent 2026-08-25 9.1 Critical
A path traversal vulnerability in Tenable Agent 11.2.0 and 11.1.3 and lower allows a privileged attacker to write arbitrary files outside the intended plugin directory, potentially leading to remote code execution.
CVE-2026-57910 1 Watchguard 2 Agent, Watchguard Agent 2026-08-25 N/A
Improper authentication in the WatchGuard Agent allows an unauthenticated attacker with network access to cause the agent to execute arbitrary code with elevated privileges.
CVE-2026-50720 1 Opensensor 1 Ingenic T31 2026-08-24 6.4 Medium
The Ingenic T31 SoC boot ROM flash-boot verification path compares only a single 32-bit word of the RSA signature output against a single 32-bit word of the SHA-256 payload digest, rather than compare the full data. This allows an attacker with physical write access to boot media to forge modified SPL (Secondary Program Loader) images that pass secure boot verification without possession of the OEM signing key. Each forgery attempt succeeds with approximately 2/3 probability. This has been validated via reverse engineering, software emulation against vendor-signed images, and end-to-end hardware acceptance of a forged firmware image on a Wyze Video Doorbell v2 (T31X).
CVE-2026-50719 1 Opensensor 1 Ingenic T31 2026-08-24 6.8 Medium
The Ingenic T41, and probably also T32, T40, and A1 SoC boot ROMs parse and execute an attacker-controlled init table from the SPL header before checking the secure boot state and before invoking signature verification. The init table parser supports full-address 32-bit write operations, allowing modification of SRAM-resident secure boot state prior to the verification decision. An attacker with physical write access to boot media can inject an init-table entry that disables the secure boot check, causing the ROM to accept unsigned or modified first-stage boot code. This has been hardware-validated on a secureboot-enabled T41 device; ROM analysis confirms closely related behavior on T32, T40, and A1.
CVE-2021-43716 1 Epson 1 Easymp Network Updater 2026-08-24 9.8 Critical
Verification Bypass vulnerability exists in EPSON 150075647YWWV110 EasyMP Network Updater Ver.1.20. The Epson projector can be updated by encrypted firmware through USB.
CVE-2020-3138 1 Cisco 1 Enterprise Nfv Infrastructure Software 2026-08-24 6.7 Medium
A vulnerability in the upgrade component of Cisco Enterprise NFV Infrastructure Software (NFVIS) could allow an authenticated, local attacker to install a malicious file when upgrading. The vulnerability is due to insufficient signature validation. An attacker could exploit this vulnerability by providing a crafted upgrade file. A successful exploit could allow the attacker to upload crafted code to the affected device.
CVE-2026-62834 1 Microsoft 1 Azure Data Factory 2026-08-24 9.3 Critical
Improper verification of cryptographic signature in Azure Data Factory allows an unauthorized attacker to elevate privileges over a network.
CVE-2026-15556 1 Redhat 4 Jboss Enterprise Application Platform, Jboss Enterprise Application Platform Els, Jboss Enterprise Application Platform Expansion Pack and 1 more 2026-08-24 8.1 High
A flaw was found in Picketlink's SP signature validation; a SAML response containing zero assertion elements matching the signature check can allow an attacker to forge a SAML response and auth as any principal with any roles on the protected application.
CVE-2026-75946 1 Hp Inc 1 Omen Gaming Hub 2026-08-21 N/A
A potential security vulnerability has been identified in the OMEN Gaming Hub for versions prior to 1101.2608.0.0. The vulnerability could potentially allow a local attacker to escalate privileges due to insufficient access controls.
CVE-2025-9210 1 Otalio 1 Ship Property Management System 2026-08-21 8.1 High
Missing signature validation in JSON Web Tokens in Otalio Ship Property Management System versions before 2.22.0 allows authenticated attackers to escalate privileges via tampering with JWTs
CVE-2026-76234 1 Celabshq 1 Libcrux 2026-08-21 7.5 High
libcrux-ecdh and libcrux-ed25519 before 0.0.6, and libcrux-psq before 0.0.7, contain cryptographic implementation bugs. libcrux-ecdh did not properly check length and clamping during X25519 secret validation (and had a broken clamping check for imported X25519 secret keys); libcrux-ed25519 performed a duplicated clamping step during key generation; and libcrux-psq panicked instead of propagating an AEADError. These were fixed in the respective patched releases.
