CVE-2026-50634 Medium · 6.5 CWE-347 Jun 12, 2026

Apache CXF: WS JSON request filter trusts metadata from an unvalidated first signature entry

A vulnerability in Apache CXF's JwsJsonContainerRequestFilter can be exploited to cause CXF to process metadata that was not authenticated by the accepted signature. This can bypass the application's assumption that accepted `Content-Type` or protected HTTP-header metadata came from a verified signature entry, and may steer downstream JAX-RS entity parsing or signed-header consistency checks.

CVE-2026-50631 High · 7.4 CWE-367 Jun 12, 2026

Apache CXF: OAuth2: TOCTOU Race Condition in Refresh Token Processing

A race condition in AbstractOAuthDataProvider allows concurrent requests using the same Refresh Token to bypass single-use semantics and generate multiple valid Access Tokens, when 'recycleRefreshTokens' is set to false. A leaked refresh token can be replayed concurrently by multiple attackers or threads. Users are recommended to upgrade to versions 4.2.2 or 4.1.7 or 3.6.12, which fixes this issue.

CVE-2026-50630 Medium · 6.5 CWE-113 Jun 12, 2026

Apache CXF: OAuth2: HTTP Response Splitting via WWW-Authenticate Realm Injection

A CRLF injection vulnerability exists in the OAuth2 AuthorizationUtils class. When constructing the WWW-Authenticate response header, the 'realm' parameter is concatenated without sanitizing Carriage Return (CR) and Line Feed (LF) characters. If an attacker can control the realm value, they can inject arbitrary HTTP headers or split the HTTP response entirely. Users are recommended to upgrade to versions 4.2.2 or 4.1.7 or 3.6.12, which fixes this issue.

CVE-2026-50629 Medium · 5.3 CWE-93 Jun 12, 2026

The 'clientId' parameter from incoming HTTP requests is directly concatenated into OAuth2 server log warning messages without sanitizing control characters. This allows an attacker to inject arbitrary content, including fake log entries, into the server's log files. Users are recommended to upgrade to versions 4.2.2 or 4.1.7 or 3.6.12, which fixes this issue.

CVE-2026-50628 Critical · 9.8 CWE-20 Jun 12, 2026

Apache CXF: OAuth2: Inverted IP Binding Check Defeats Security Control

A logic error in OAuthRequestFilter rejects legitimate requests originating from the bound IP address, while blindly allowing requests from any other IP address. Enabling this security feature inadvertently creates an inverse security check. Users are recommended to upgrade to versions 4.2.2 or 4.1.7 or 3.6.12, which fixes this issue.

CVE-2026-50627 Critical · 9.1 CWE-289 Jun 12, 2026

Apache CXF: OAuth2: Missing JWT Audience and Issuer Validation in Access Token Validator

The JwtAccessTokenValidator class in Apache CXF fails to validate the 'aud' (Audience) claims of incoming JWT access tokens. This allows a JWT issued for one Resource Server to be successfully replayed against a completely different Resource Server, leading to Token Confusion/Routing attacks. Users are recommended to upgrade to versions 4.2.2 or 4.1.7 or 3.6.12, which fixes this issue.

CVE-2026-50623 Medium · 4.8 CWE-287 Jun 12, 2026

Apache CXF: Authentication Bypass in OAuth2 TokenIntrospectionService

An authentication bypass vulnerability exists in the OAuth2 TokenIntrospectionService in Apache CXF. Due to a missing 'throw' keyword in the security context check, the introspection endpoint (/services/oauth2/introspect) can be accessed by any unauthenticated network attacker. However note that this is a safeguard only in the case that someone forgot to enable authentication on the service. Users are recommended to upgrade to version 4.2.2 or 4.1.7 or 3.6.12, which fixes this issue.

CVE-2026-49875 Critical · 9.8 CWE-611 Jun 12, 2026

Apache CXF's EndpointReferenceUtils and W3CMultiSchemaFactory classes construct a SAXParserFactory without the necessary JAXP hardening configurations, enabling out-of-band (OOB) external entity resolution. Users are recommended to upgrade to versions 4.2.2 or 4.1.7 or 3.6.12, which fix this issue.

CVE-2026-50223 High · 8.8 CWE-94 Jun 10, 2026

Apache OFBiz: DataResource Low-Privileged Authenticated FreeMarker Template Injection Leads to Remote Code Execution

Improper Control of Generation of Code ('Code Injection') vulnerability in Apache OFBiz allows a low-privileged authenticated user with Content/DataResource editing privileges to perform template injection attacks that could lead to Remote Code Execution. This issue affects Apache OFBiz: before 24.09.07. Users are recommended to upgrade to version 24.09.07, which fixes the issue.

CVE-2026-47342 High · 8.8 CWE-285 Jun 10, 2026

Improper Restriction of Security Token Assignment vulnerability in Apache Answer. This issue affects Apache Answer: through 2.0.0. Previously issued administrative tokens were not invalidated after an administrator account was suspended, deleted, or deactivated, allowing continued access to administrative APIs until the token expired. Users are recommended to upgrade to version 2.0.1, which fixes the issue.

CVE-2026-49818 Medium · 6.5 CWE-22 Jun 9, 2026

Apache Airflow Samba provider: Path traversal in GCSToSambaOperator via GCS object names

The Apache Airflow Samba provider's `GCSToSambaOperator` joined GCS object names to the SMB destination path without a containment check, so an object named with `../` segments resolved a write path outside the configured `destination_path`. An attacker able to write objects into the source GCS bucket — typically an external data producer distinct from the trusted DAG author — could write files to arbitrary locations on the Samba target when the operator ran. Upgrade apache-airflow-providers-samba to 4.12.6 or later, which validates the resolved destination stays within `destination_path`.

CVE-2026-34905 Medium · 6.5 CWE-200 Jun 9, 2026

Apache Answer: Unlisted Questions Accessible via Direct API Access

Exposure of Sensitive Information to an Unauthorized Actor vulnerability in Apache Answer. This issue affects Apache Answer: through 2.0.0.
