CVE-2026-45754 MEDIUM PATCH GHSA This Month

Unauthenticated webhook event injection in Symfony's Mailjet Mailer and LOX24 SMS Notifier bridges allows remote attackers to POST arbitrary forged payloads to an application's webhook endpoint, even when a webhook secret is configured. The root cause is that both `MailjetRequestParser::doParse()` and `Lox24RequestParser::doParse()` accept a secret parameter but silently discard it, returning the payload unconditionally. Attackers who can discover the webhook URL can fabricate bounce, spam, open, click, or delivery events, leading to suppression-list corruption and delivery-metrics fraud. No public exploit has been identified at time of analysis and this vulnerability is not listed in CISA KEV.

CVE-2026-48526 HIGH PATCH This Week

Authentication bypass in PyJWT versions prior to 2.13.0 allows remote attackers to forge valid JSON Web Tokens by exploiting an algorithm confusion flaw where the library fails to validate that a JSON Web Key intended for asymmetric verification is not reused as an HMAC shared secret. An attacker who knows the issuer's public key (typically distributed openly via JWKS endpoints) can sign HMAC-algorithm tokens with that public key and have them accepted as legitimate. No public exploit identified at time of analysis, though the underlying algorithm-confusion class is a well-documented JWT attack pattern.

Unauthenticated password reset in Mennekes Amtron EV charging stations running firmware 5.22.3 and earlier allows remote attackers to seize the operator account by sending a crafted POST to /operator/operator. CVSS 4.0 of 9.3 with PR:N/UI:N and CWE-287 reflects a complete authentication bypass, and the CVSS exploit maturity flag (E:P) plus the cyberdanube research disclosure indicate publicly available exploit code exists, though the vulnerability is not currently listed in CISA KEV.

CVE-2026-47272 HIGH PATCH This Week

Authentication bypass in pam_usb prior to 0.9.0 lets a local user defeat the USB hardware-authentication factor by deleting their own ~/.pamusb/device.pad file. The flawed pusb_pad_compare() check in src/pad.c only confirmed the user-side pad was readable and treated its absence as a non-fatal failure in certain code paths, so authentication succeeded without the physical USB device ever being verified. There is no public exploit identified at time of analysis, but the technique is trivial - a single file deletion by the account owner.

Authentication bypass in IBM Aspera High-Speed Transfer Server for Cloud Pak for Integration (CP4I) versions 1.5.1 through 1.5.19 allows remote attackers to access and modify protected resources without valid credentials, scoring CVSS 9.1 critical. The flaw exposes confidential file transfer data and permits unauthorized modification of integrity-protected assets across all affected releases. No public exploit identified at time of analysis, and EPSS predicts only a 0.02% near-term exploitation probability despite the high severity rating.

CVE-2026-8994 HIGH This Week

Authentication bypass in the Login with NEAR WordPress plugin (all versions through 0.3.3) lets unauthenticated attackers log in as any existing user - including administrators - whose email matches the deterministic <account>@near.org pattern. The flaw stems from the unauthenticated ajaxLoginWithNear() handler issuing a valid WordPress auth cookie based only on a substring check for '.near', with no signature, challenge-response, or nonce verification. No public exploit identified at time of analysis, and EPSS exploitation probability is low (0.10%), but the technical impact is total per CISA SSVC.

CVE-2026-44847 HIGH PATCH This Week

Authentication bypass in MaxKB (1Panel-dev) versions prior to 2.9.0 allows remote unauthenticated attackers to invoke webhook trigger endpoints and execute their bound tasks. The flaw stems from the WebhookAuth class unconditionally returning a successful authentication tuple, which Django REST Framework interprets as a valid identity, combined with no backend enforcement of per-trigger token requirements. No public exploit identified at time of analysis, but the trivial nature of the bypass and open-source visibility of the patch make exploitation straightforward for any attacker who can enumerate or guess trigger IDs.

Improper authentication in JeecgBoot 3.9.1 OpenAPI endpoint allows remote attackers to bypass authentication checks and perform unauthorized actions, though exploitation is rated difficult due to high attack complexity. No public exploit code has been identified and no vendor response has been received. With CVSS 3.7 (Low severity) and AV:N/AC:H/PR:N parameters, the vulnerability poses limited immediate risk but requires monitoring given the authentication bypass nature and remote attack vector.

Privilege elevation in Microsoft Azure Resource Manager (ARM) allows remote unauthenticated attackers to bypass authentication and gain elevated privileges across the cloud control plane. The flaw carries a maximum CVSS score of 10.0 due to a scope change combined with full confidentiality, integrity, and availability impact, and although Microsoft has released a fix there is no public exploit identified at time of analysis. Given ARM is the central management layer for nearly all Azure resources, successful exploitation could have broad tenant-wide consequences.

Authentication bypass in Best Practical's Request Tracker (RT) versions 5.0.9 and prior, and 6.0.0 through 6.0.2, allows remote attackers to log in as any LDAP-backed user without valid credentials when RT is configured with LDAP or Active Directory authentication and the LDAP server accepts unauthenticated bind requests. The flaw, fixed in RT 5.0.10 and 6.0.3 released 2026-05-20, carries a CVSS 8.1 and has no public exploit identified at time of analysis, but the trivial nature of the bypass against vulnerable LDAP policies makes it high-priority for any RT deployment using directory-based auth.
