Incorrect implementation of authentication algorithm vulnerability in Apache Answer. This issue affects Apache Answer: through 2.0.2. A flaw in the User Center login integration can cause a newly created external user session to omit its external identity, allowing subsequent requests to bypass central account suspension or deletion checks until the session expires or is revoked. Users are recommended to upgrade to version 2.0.3, which fixes the issue.

——10Incorrect implementation of authentication algorithm vulnerability in Progress MOVEit Transfer (SFTP module).
This issue affects MOVEit Transfer: before 2025.1.6 and from 2026.0.0 before 2026.0.4.1dCVE-2026-1049397.5 HIG28.2%
——8Description
NGINX Ingress Controller has a vulnerability when implementing an externalAuth policy for ingress. NGINX Ingress Controller may mishandle the HTTP response from an OAuth IdP and allow an attacker to acquire unauthenticated access to protected paths before the proper external authentication can happen.
Impact
This vulnerability may allow remote attackers
unauthenticated
access to protected
paths. There is no control plane exposure; this is a data plane issue only.
Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.5dCVE-2026-839066.5 MED58.8%
——18Incorrect implementation of authentication algorithm in Windows Shell allows an unauthorized attacker to perform spoofing over a network.7dCVE-2026-859727.4 HIG15.4%
——5Progress MarkLogic Server 12.x releases before 12.1.0 and 11.x releases before 11.3.7 do not sufficiently verify the identity of a Kerberos authentication service in certain password-based authentication configurations. A network-positioned attacker could impersonate trusted authentication infrastructure, potentially resulting in unauthorized access or modification of protected data.5dCVE-2026-107279—28.1%
——8The AsyncHttpClient (AHC) library allows Java applications to easily execute HTTP requests and asynchronously process HTTP responses. In 3.0.12, a peer offering only Digest qop=auth-int causes mutual-authentication verification to be skipped. AuthenticatorUtils.computeExpectedRspAuth returns no expected value for auth-int, and Interceptors treats that result as unverifiable but nonfatal, so a response with an invalid rspauth value is accepted. A peer that does not know the shared secret can therefore be accepted as the authenticated server. This issue is fixed in version 3.0.13.12dCVE-2026-977209.1 CRI23.9%
——7Incorrect implementation of JWT/OAuth authentication in Impala executors in Apache Impala versions up to and including 4.5.2 which allows attacked to access resources served by the executor's webserver when that webserver is configured to accept JWT/OAuth tokens. Bearer token (JWT) signatures are not validated resulting in the webserver accepting any valid JWT.
Users are recommended to either disable JWT/OAuth auth for Impala executors or upgrade to version 4.5.3, which fixes this issue.13d
