Not enough EPSS history yet.
In Apache CXF's DefaultEncryptingCodeDataProvider, a captured authorization code can be redeemed an unlimited number of times due to a flaw in the implementation of the removeCodeGrant functionality. This violates the RFC requirement that "The authorization code MUST NOT be used more than once." Users are recommended to upgrade to versions 4.2.3 or 4.1.8 or 3.6.12, which fix this issue.

CVE-2026-189676.4 MED—
——0A flaw was found in the SAML broker component of Keycloak, an identity and access management solution. When configured as a SAML broker using the IdP-Initiated flow, Keycloak fails to enforce the OneTimeUse condition in SAML assertions. This allows an attacker who captures a valid, unused assertion to replay it multiple times. Successful exploitation could allow an attacker to hijack a user's session and gain unauthorized access to the system as that user.6hCVE-2026-53431—34.0%
——10Authentication Bypass by Capture-replay vulnerability in malach-it Boruta allows an attacker who has obtained a previously valid JWT client assertion to authenticate as the issuing OAuth client after the assertion has expired.
Boruta accepts JWT-based client authentication (client_secret_jwt and private_key_jwt token endpoint authentication methods) but never enforces that the assertion's exp claim is in the future. The pre-check helper Boruta.Oauth.Request.Base.check_expiration/1 in lib/boruta/oauth/request/base.ex only verifies that an exp claim is present (it pattern-matches on the existence of the key and returns success), and the Joken token configuration used for signature verification, Boruta.Oauth.Authorization.Client.Token.token_config/0 in lib/boruta/oauth/authorization/client.ex, returns an empty map, so Joken's default exp claim validator is not engaged either. Any attacker who obtains a validly-signed client assertion (for example through logs, reverse proxies, browser tooling, or other observability surfaces) can replay it indefinitely to authenticate as the client and obtain access tokens with that client's privileges.
This issue affects boruta: from 2.3.0 before 2.3.7.7dCVE-2026-156147.5 HIG13.8%
——4Logto silently fails to delete IdP-initiated SAML sessions, enabling session replay and reuse within the session’s validity window.10dCVE-2026-47133—1.3%
——0ClearanceKit intercepts file-system access events on macOS and enforces per-process access policies. Prior to version 5.0.10, each table in the on-disk SQLite policy store (`/Library/Application Support/clearancekit/store.db`) is verified using an ECDSA signature stored in the `data_signatures` table. The signed payload contains only the canonical row content, with no version counter or freshness binding. An attacker who can write `store.db` and the matching `data_signatures` row — feasible during the opfilter-update window when the Endpoint Security filter is offline, or via offline-boot / decrypted-backup scenarios — can substitute a previously-captured legitimately-signed snapshot. opfilter accepts the older snapshot as fully valid on next boot because the existing signatures still verify. Version 5.0.10 patches the issue.14dCVE-2026-160835.3 MED35.4%
——11A security flaw has been discovered in Sipeed PicoClaw up to 0.2.9. This affects the function webhook.ParseRequest of the file pkg/channels/line/line.go of the component LINE Webhook. The manipulation results in authentication bypass by capture-replay. The attack may be launched remotely. The exploit has been released to the public and may be used for attacks. The reported GitHub issue was closed automatically with the label "not planned" by a bot.17dCVE-2026-564535.5 MED8.5%
——3HCL DFXAnalytics is affected by an Account Takeover via Response Manipulation vulnerability. A remote attacker can intercept and alter the contents of the server's HTTP responses before they reach the client application, allowing them to manipulate the authentication or authorization logic to bypass controls and gain unauthorized access to targeted user accounts.20d
