CVE-2026-53501 1 Thumbor 1 Thumbor 2026-08-02 8.2 High
Thumbor is an open-source photo thumbnail service by globo.com. Prior to 7.8.0, Thumbor’s HMAC validation can be bypassed due to the use of Python’s .replace() when removing the signature from the URL before validation. Since .replace() removes all occurrences of the substring, an attacker can insert the same signature multiple times in the URL and manipulate the final URL used for validation. This allows crafting URLs where the validated string differs from the actual requested resource, enabling loading images from unintended domains or paths. This issue is fixed in 7.8.0.
CVE-2026-54787 2 Redhat, Sigstore 2 Hummingbird, Sigstore-go 2026-08-02 3.1 Low
sigstore-go is a Go library for Sigstore signing and verification. Prior to 1.2.1, sigstore-go does not check a bundle signing timestamp against the validity window of an ExpiringKey wrapping a self-managed long-lived signing key without a certificate, which can allow an attacker holding expired key material to sign accepted bundles. This issue is fixed in version 1.2.1.
CVE-2026-56451 2026-07-31 10 Critical
A vulnerability has been identified in Opcenter X (All versions < V2604). Affected applications do not properly validate the algorithm specified in the JSON Web Token (JWT) header. This could allow an unauthenticated remote attacker to forge arbitrary JWT, bypass authentication mechanisms and impersonate any user including administrative accounts, potentially gaining full unauthorized access to the application.
CVE-2026-48815 1 Sigstore 1 Sigstore 2026-07-30 7.5 High
sigstore-js provides JavaScript libraries for interacting with Sigstore services. Prior to 4.1.1, the documented certificateOIDs option in sigstore.verify() is accepted by the public API but discarded before verification, so required certificate extension OIDs are never checked and applications relying on certificateOIDs to restrict which certificates may sign artifacts can accept unauthorized certificates. This issue is fixed in version 4.1.1.
CVE-2026-48758 1 Sigstore 1 Sigstore 2026-07-30 5.4 Medium
sigstore-js provides JavaScript libraries for interacting with Sigstore services. Prior to 3.2.1, the preAuthEncoding function in @sigstore/core uses Node.js ascii encoding when converting the PAE string to bytes, allowing payloadType to be mutated after signing without invalidating the signature and breaking the type-binding guarantee that DSSE is designed to provide. This issue is fixed in version 3.2.1.
CVE-2026-45795 1 Jansson Project 1 Jansson 2026-07-30 5.3 Medium
The Janssen Project is an open-source identity and access management (IAM) platform. Prior to 2.0.0, jans-auth-server accepts unsigned JWE request objects because JwtAuthorizationRequest skips inner signature validation when jwe.getSignedJWTPayload() returns null, and AuthzRequestService.processRequestObject() does not reject the unrecognized RSA-OAEP algorithm when forceSignedRequestObject=true. This issue is fixed in version 2.0.0.
CVE-2026-17872 1 Google 2 Android, Chrome 2026-07-30 6.1 Medium
Cryptographic Flaw in WebAppInstalls in Google Chrome on Android prior to 151.0.7922.72 allowed a local attacker to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: Medium)
CVE-2026-13305 1 Autel 1 Maxicharger Ac Elite Home 2026-07-30 N/A
Autel MaxiCharger AC Elite Home Software Update Improper Verification of Cryptographic Signature Arbitrary Code Execution Vulnerability. This vulnerability allows physically present attackers to execute arbitrary code on affected installations of Autel MaxiCharger AC Elite Home EV chargers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of software updates. The issue results from the lack of proper validation of a user-supplied software update image. An attacker can leverage this vulnerability to execute code in the context of the device. Was ZDI-CAN-29062.
CVE-2026-17666 1 Google 1 Chrome 2026-07-30 9.1 Critical
Cryptographic Flaw in Enterprise in Google Chrome prior to 151.0.7922.72 allowed an attacker in a privileged network position to bypass discretionary access control via malicious network traffic. (Chromium security severity: High)
CVE-2026-44104 2 Phoenix Contact, Phoenixcontact 8 Charx Sec 3000, Charx Sec 3050, Charx Sec 3100 and 5 more 2026-07-30 9.8 Critical
The firmware update process for the basemodule of the charging controller only validates the CRC32 checksum without cryptographic signature verification. This allows an unauthenticated remote attacker to install a modified firmware, resulting in full system compromise.
CVE-2026-59243 1 Apache 2 Airflow Fab Provider, Apache-airflow-providers-fab 2026-07-29 9.8 Critical
The FAB auth manager's Azure AD OAuth login defaulted `verify_signature=False` when decoding the ID token, so an attacker able to present a forged or unsigned (`alg:none`) ID token to the OAuth callback could bypass authentication and log in as an arbitrary user, including one holding the Admin role (CWE-347). Deployments running the FAB auth manager with the Azure AD OAuth login path under its default configuration are affected; the Authentik path already defaulted to `True`. This issue affects `apache-airflow-providers-fab` before 3.7.3. Users are advised to upgrade to `apache-airflow-providers-fab` 3.7.3, which defaults `verify_signature=True`.
CVE-2026-63237 1 Three Learning 1 Koollab Lms 2026-07-29 4.8 Medium
A TOTP two-factor authentication bypass vulnerability in Koollab LMS allowed an attacker to supply a client-controlled seed to generate a matching one-time password and bypass the second authentication factor, potentially enabling unauthorised access to administrator accounts.
CVE-2026-49834 1 Sigstore 1 Sigstore-go 2026-07-28 5.9 Medium
sigstore-go is a Go library for Sigstore signing and verification. Prior to 1.2.0, a verifier configured with WithTransparencyLog(N>1) or WithSignedCertificateTimestamps(N>1) counts verified witnesses per entry or per validation path rather than per log authority, allowing a single compromised transparency log or CT log to satisfy multi-log threshold requirements and defeat the multi-log policy. This issue is fixed in version 1.2.0.
CVE-2026-65616 1 Jfrog 1 Artifactory 2026-07-28 8.8 High
Incorrect authorization validation in refresh token signature allows non-admin users to obtain a signed JFrog administrator token.
CVE-2026-13089 1 Ritou 1 Oidc::lite 2026-07-27 7.5 High
OIDC::Lite versions through 0.12.1 for Perl allow ID Token signature verification bypass via a token-controlled algorithm allowlist in verify. When the caller does not pin an algorithm, OIDC::Lite::Model::IDToken::verify sets $self->alg($self->header->{alg}) from the token's own header and then calls decode_jwt(token, key, 1, [$self->alg]), handing JSON::WebToken an accepted-algorithm allowlist taken from the untrusted token. A token with alg=none yields ['none'], so decode_jwt returns the claims with no signature check, and a token with alg=HS256 is verified with the RP's RSA public key as the HMAC secret (RS to HS confusion). The ID Token is the OpenID Connect authentication assertion delivered to the Relying Party. Any caller that verifies an ID Token through the unpinned load(token)->verify path, or load(token, key) with only the key pinned, accepts a forged token carrying attacker-chosen claims such as sub and is authenticated as any user. Passing an explicit algorithm so $self->alg is already set bypasses the header-derived allowlist and is not affected. Note that the latest version uploaded to CPAN is 0.10. Later versions are available in the git repository.
CVE-2026-14837 1 Lenze 7 C430, C4xx Firmware, C550 and 4 more 2026-07-27 7.8 High
Multiple Lenze products are affected by an improper signature verification vulnerability in the SSH enablement mechanism. A low-privileged local attacker can bypass verification of the SSH enable file signature and enable SSH access on the device. Successful exploitation may result in unauthorized administrative access and complete system compromise.
CVE-2026-45755 2 Sensiolabs, Symfony 3 Symfony, Mailtrap-mailer, Symfony 2026-07-27 5.3 Medium
Symfony is a PHP framework for web and console applications and a set of reusable PHP components. Prior to 7.4.12 and 8.0.12, MailtrapRequestParser::doParse() received the configured webhook secret but ignored the X-Mt-Signature HMAC header, allowing unauthenticated POST requests to inject forged Mailtrap delivery, bounce, open, click, or spam events. This issue is fixed in versions 7.4.12 and 8.0.12.
CVE-2026-47212 2 Sensiolabs, Symfony 3 Symfony, Symfony, Twilio-notifier 2026-07-27 5.3 Medium
Symfony is a PHP framework for web and console applications and a set of reusable PHP components. Prior to 6.4.40, 7.4.12, and 8.0.12, TwilioRequestParser::doParse() received the configured webhook secret but ignored the X-Twilio-Signature HMAC header, allowing unauthenticated POST requests to inject forged Twilio status payloads. This issue is fixed in versions 6.4.40, 7.4.12, and 8.0.12.
CVE-2026-48747 2 Sensiolabs, Symfony 3 Symfony, Mailomat-mailer, Symfony 2026-07-27 5.3 Medium
Symfony is a PHP framework for web and console applications and a set of reusable PHP components. Prior to 7.4.13 and 8.0.13, MailomatRequestParser::validateSignature() parsed X-MOM-Webhook-Signature as algo=signature and passed the request-selected algorithm to hash_hmac(), allowing a signature algorithm downgrade instead of enforcing Mailomat's documented SHA-256 webhook signature. This issue is fixed in versions 7.4.13 and 8.0.13.
CVE-2026-48021 1 Med-united 1 Epa4all 2026-07-27 9.1 Critical
In epa4all, prior to version 2026-05-20, an attacker who can intercept the TLS connection between epa4all and the ePA backend can complete the VAU handshake with attacker-controlled keys and obtain the session encryption keys. All inner HTTP traffic (patient consent decisions, medication data, document operations, authorization tokens, and entitlement queries) becomes readable and modifiable. The attacker can also inject arbitrary requests through the hijacked channel. This issue has been patched in version 2026-05-20.
