CVE-2026-16742 2026-09-01 N/A 6.7 MEDIUM
systemd-homed contains a local privilege escalation bug via arbitrary system group addition to a local, logged in, homed-managed user
CVE-2026-81700 1 Jahlives 1 Openssl Encrypt 2026-09-01 N/A 9.8 CRITICAL
openssl_encrypt versions before 1.4.9 contain a signature verification vulnerability in gpg_runner.verify_detached that accepts revoked and expired keys by only checking VALIDSIG status without inspecting REVKEYSIG, EXPKEYSIG, or gpg exit codes. Attackers holding compromised-then-revoked signing keys or expired project keys can bypass signature verification to execute malicious plugins in the host process.
CVE-2026-81701 1 Jahlives 1 Openssl Encrypt 2026-09-01 N/A 9.8 CRITICAL
openssl_encrypt versions before 1.4.9 use a denylist to identify trusted built-in plugins, allowing unsigned plugins in top-level plugins/ directories and unknown subdirectories to bypass signature verification. Attackers can place malicious unsigned plugins following documented installation paths to achieve arbitrary code execution in the CLI process with access to passwords and cryptographic keys.
CVE-2026-74901 1 Jahlives 1 Openssl Encrypt 2026-09-01 N/A 9.8 CRITICAL
openssl_encrypt versions before 1.4.0 contain an authentication bypass vulnerability in pqc.py where AES-GCM decryption failures trigger fallback to unauthenticated AES-CTR mode. Attackers can modify ciphertext in transit to bypass integrity verification and perform bit-flipping attacks without detection.
CVE-2026-74876 1 Jahlives 1 Openssl Encrypt 2026-09-01 N/A 9.8 CRITICAL
openssl_encrypt versions before 1.4.0 contain a vulnerability in PublicKeyBundle.from_dict() that creates key bundles from untrusted data without verifying signatures. Attackers can call from_dict() followed by to_identity() without signature verification to encrypt data using attacker-controlled public keys, leaking secrets.
CVE-2026-10579 2026-09-01 N/A 9.8 CRITICAL
A flaw was found in Picketlink Federation SAML; the unsolcited response handler would accept forged assertions with no verification or validation, permitting an unauthed attacker to authenticate as any principal in any role. This could lead to information disclosure, access to restricted operations, or other flaws.
CVE-2026-82645 2026-08-31 N/A 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-2026-12263 2026-08-31 N/A 8.8 HIGH
Zohocorp ManageEngine Password Manager Pro versions before 13232 and PAM360 versions before 8551 are vulnerable to an authentication bypass vulnerability due to improper SAML validation.
CVE-2025-9210 2026-08-31 N/A 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-2026-75946 2026-08-31 N/A 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-2026-82454 2026-08-31 N/A 9.1 CRITICAL
The Omnivore API (packages/api) before the fix in commit abf53d6 contains an authentication bypass in Apple sign-in token verification. The decodeAppleToken function extracted the 'alg' field from the attacker-supplied JWT header and passed it as the sole allowed algorithm to jwt.verify(). Using jsonwebtoken v8 (which does not validate key/algorithm compatibility), an attacker can set alg=HS256 and sign a forged token using Apple's publicly available RSA public key as the HMAC secret, bypassing signature verification and impersonating any Apple-linked account.
CVE-2026-58085 1 Freebsd 1 Freebsd 2026-08-31 N/A 7.5 HIGH
After dispatching a decrypt operation to OCF and receiving the result, the wg(4) driver failed to check whether the MAC verification step succeeded. The driver thus silently accepted packets with an invalid Poly1305 authentication tag. A remote attacker who can send UDP packets to a WireGuard endpoint, and who can guess the bounds of the receiver's replay window, can inject forged or modified transport data packets into the tunnel. A remote attacker who can intercept WireGuard packets bound for a FreeBSD host can modify the ciphertext and authenticated data without detection by the receiver.
CVE-2026-76581 2026-08-28 N/A 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-2026-12860 1 Bouncycastle 2 Bc-java, Bouncy Castle For Java Lts 2026-08-28 N/A 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-2026-59639 1 Bouncycastle 3 Bc-java, Bcpkix-fips, Bouncy Castle For Java Lts 2026-08-28 N/A 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-2026-13722 1 Watchguard 39 Firebox Cloud, Firebox M270, Firebox M290 and 36 more 2026-08-28 N/A 7.2 HIGH
WatchGuard Fireware OS contains a firmware validation bypass when processing a backup image via the backup/restore feature. An authenticated administrator can exploit this vulnerability to install a tampered firmware image.
CVE-2026-68745 1 Apache 1 Cloudstack 2026-08-27 N/A 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-2026-72889 2026-08-26 N/A 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 N/A 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-2020-3138 1 Cisco 1 Enterprise Nfv Infrastructure Software 2026-08-24 7.2 HIGH 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.
