The Quick Event Manager WordPress plugin before 9.19 does not verify the authenticity of PayPal payment notifications before marking event registrations as paid, which could allow unauthenticated attackers to mark registrations as paid without making a payment.

CVE-2025-66621——
———Apache James SASL OAuthBearer/XOAUTH2 prior versions 3.9.1 fails to validate correctly AUD claim of JWT payloads when introspection is not configured.
This allows an attacker with valid credentials to access the mail server even if they are not authorized to do so.
We recommend users to upgrade to non vulnerable version that forces explicit configuration of aud claims and forces introspection.7hCVE-2026-1216335.3 MED—
———The Order Tracking WordPress plugin before 3.6.0 does not verify that a PayPal payment notification was sent to the merchant's account, or that its amount matches the order total, before marking an order as paid, which could allow unauthenticated attackers to mark arbitrary orders as paid using a trivial payment to their own PayPal account.7hCVE-2026-889825.4 MED—
———Kubeflow Pipelines enables users to build and deploy portable, scalable machine learning workflows. Prior to 2.18.0, the legacy V1/raw-Argo execution cache mutating webhook and cache-server storage path hash selected template fields without the Kubernetes namespace, use the key alone for lookups and duplicate checks, and trust the mutable pipelines.kubeflow.org/execution_cache_key annotation when publishing outputs. In multi-user deployments where tenant namespaces share the cache service, a tenant with workload-submission privileges can read another namespace's cached outputs or seed matching outputs that are substituted into a later step. Standard KFP V2 component pods bypass this cache, matching requires the selected template fields and staleness policy, and arbitrary code execution or service availability impact is not established. This issue is fixed in version 2.18.0.20hCVE-2026-1157709.6 CRÍ6.0%
——2Pocket ID is an OIDC provider that allows users to authenticate with their passkeys to services. From 2.2.0 until 2.12.0, SendEmailVerification uses the token model in backend/internal/model/email_verification_token.go to bind an email-verification token only to the user's identifier, while UpdateUser can change the account email without invalidating the outstanding token and VerifyEmail marks the current address as verified. An ordinary user can request a token for an address they control, change the account to an arbitrary unused address, and redeem the old token so Pocket ID publishes the new address with email_verified set to true. The default affected configuration uses emailsVerified=false and allowOwnAccountEdit=true; the target address must not already belong to another Pocket ID user. A relying application that trusts a verified email for automatic account matching or provisioning can link the attacker's identity to another user's account, while applications that rely exclusively on the stable OIDC sub claim are not affected by that downstream consequence. This issue is fixed in version 2.12.0.2dCVE-2026-121637—18.4%
——6An improper integrity validation vulnerability in WatchGuard AuthPoint Gateway's LDAP authentication callback allows a network attacker who has obtained a valid header signature to forge the authentication result and transaction identifier in the request body, resulting in unauthorized session outcomes.2dCVE-2026-1216206.5 MED12.7%
——4CoopCycle coopcycle-web 5.6.0 before 6.20.0 contains a missing authentication vulnerability that allows unauthenticated attackers to forge Zelty webhook events because the x-zelty-hmac-sha256 HMAC signature is never verified. Attackers can POST forged dish, menu, option and order-status events to /api/zelty/webhook/* endpoints to toggle restaurant products and alter order preparation states.2d
