Description

Langflow is a tool for building and deploying AI-powered agents and workflows. In versions prior to 1.9.0, the POST /api/v1/build_public_tmp/{flow_id}/flow endpoint allows building public flows without requiring authentication. When the optional data parameter is supplied, the endpoint uses attacker-controlled flow data (containing arbitrary Python code in node definitions) instead of the stored flow data from the database. This code is passed to exec() with zero sandboxing, resulting in unauthenticated remote code execution. This is distinct from CVE-2025-3248, which fixed /api/v1/validate/code by adding authentication. The build_public_tmp endpoint is designed to be unauthenticated (for public flows) but incorrectly accepts attacker-supplied flow data containing arbitrary executable code. This issue has been fixed in version 1.9.0.

Zwei kritische Schwachstellen beherrschen die Lage für deutsche Unternehmen.
Das BSI warnt vor einer aktiv ausgenutzten Lücke in Microsoft SharePoint. Die CISA hatte die Schwachstelle am 18. März in ihren Katalog ausgenutzter Sicherheitslücken aufgenommen. CERT-EU veröffentlichte am 25. März ein Advisory und verwies auf Maßnahmen aus der ToolShell-Angriffskampagne des Vorjahres. Der CVSS-Score liegt bei 9.8 von 10 und wurde hochgestuft, nachdem sich herausstellte, dass eine Ausnutzung auch ohne Authentifizierung möglich ist.
Parallel dazu hat CERT-Bund am 24. März Alarm wegen zweier Schwachstellen in Citrix NetScaler ADC und NetScaler Gateway geschlagen. CVE-2026-3055 ermöglicht es nicht authentifizierten Angreifern, aktive Session-Token aus dem Speicher betroffener Geräte auszulesen. CVE-2026-4368 kann durch eine Race Condition zur Übernahme fremder Benutzersitzungen führen. Besonders gefährdet sind Systeme, die als SAML Identity Provider konfiguriert sind, also eine in Unternehmensumgebungen weit verbreitete Konfiguration für Single Sign-On. Sicherheitsforscher bewerten eine baldige aktive Ausnutzung als sehr wahrscheinlich.
Sofortmaßnahmen: SharePoint patchen, NetScaler aktualisieren und aktiven Sessions beenden.

CVSS v4.0

Description

Trivy is a security scanner. On March 19, 2026, a threat actor used compromised credentials to publish a malicious Trivy v0.69.4 release, force-push 76 of 77 version tags in `aquasecurity/trivy-action` to credential-stealing malware, and replace all 7 tags in `aquasecurity/setup-trivy` with malicious commits. This incident is a continuation of the supply chain attack that began in late February 2026. Following the initial disclosure on March 1, credential rotation was performed but was not atomic (not all credentials were revoked simultaneously). The attacker could have use a valid token to exfiltrate newly rotated secrets during the rotation window (which lasted a few days). This could have allowed the attacker to retain access and execute the March 19 attack. Affected components include the `aquasecurity/trivy` Go / Container image version 0.69.4, the `aquasecurity/trivy-action` GitHub Action versions 0.0.1 – 0.34.2 (76/77), and the`aquasecurity/setup-trivy` GitHub Action versions 0.2.0 – 0.2.6, prior to the recreation of 0.2.6 with a safe commit. Known safe versions include versions 0.69.2 and 0.69.3 of the Trivy binary, version 0.35.0 of trivy-action, and version 0.2.6 of setup-trivy. Additionally, take other mitigations to ensure the safety of secrets. If there is any possibility that a compromised version ran in one's environment, all secrets accessible to affected pipelines must be treated as exposed and rotated immediately. Check whether one's organization pulled or executed Trivy v0.69.4 from any source. Remove any affected artifacts immediately. Review all workflows using `aquasecurity/trivy-action` or `aquasecurity/setup-trivy`. Those who referenced a version tag rather than a full commit SHA should check workflow run logs from March 19–20, 2026 for signs of compromise. Look for repositories named `tpcp-docs` in one's GitHub organization. The presence of such a repository may indicate that the fallback exfiltration mechanism was triggered and secrets were successfully stolen. Pin GitHub Actions to full, immutable commit SHA hashes, don't use mutable version tags.

Description

strongSwan versions 4.5.0 prior to 6.0.5 contain an integer underflow vulnerability in the EAP-TTLS AVP parser that allows unauthenticated remote attackers to cause a denial of service by sending crafted AVP data with invalid length fields during IKEv2 authentication. Attackers can exploit the failure to validate AVP length fields before subtraction to trigger excessive memory allocation or NULL pointer dereference, crashing the charon IKE daemon.

Just released another entry in my blog series looking at the unpatchable vulnerabilities of Kubernetes.

Whilst the CVEs are quite old, understanding them is useful, both to understand if you need to apply mitigations and also for some of the low-level Kubernetes implementation details they involve.

Description

OpenTelemetry Java Instrumentation provides OpenTelemetry auto-instrumentation and instrumentation libraries for Java. In versions prior to 2.26.1, the RMI instrumentation registered a custom endpoint that deserialized incoming data without applying serialization filters. On JDK version 16 and earlier, an attacker with network access to a JMX or RMI port on an instrumented JVM could exploit this to potentially achieve remote code execution. All three of the following conditions must be true to exploit this vulnerability: First, OpenTelemetry Java instrumentation is attached as a Java agent (`-javaagent`) on Java 16 or earlier. Second, JMX/RMI port has been explicitly configured via `-Dcom.sun.management.jmxremote.port` and is network-reachable. Third, gadget-chain-compatible library is present on the classpath. This results in arbitrary remote code execution with the privileges of the user running the instrumented JVM. For JDK >= 17, no action is required, but upgrading is strongly encouraged. For JDK < 17, upgrade to version 2.26.1 or later. As a workaround, set the system property `-Dotel.instrumentation.rmi.enabled=false` to disable the RMI integration.

Description

In the Linux kernel, the following vulnerability has been resolved: net/packet: fix a race in packet_set_ring() and packet_notifier() When packet_set_ring() releases po->bind_lock, another thread can run packet_notifier() and process an NETDEV_UP event. This race and the fix are both similar to that of commit 15fe076edea7 ("net/packet: fix a race in packet_bind() and packet_notifier()"). There too the packet_notifier NETDEV_UP event managed to run while a po->bind_lock critical section had to be temporarily released. And the fix was similarly to temporarily set po->num to zero to keep the socket unhooked until the lock is retaken. The po->bind_lock in packet_set_ring and packet_notifier precede the introduction of git history.

Zwei kritische Schwachstellen beherrschen die Lage für deutsche Unternehmen.
Das BSI warnt vor einer aktiv ausgenutzten Lücke in Microsoft SharePoint. Die CISA hatte die Schwachstelle am 18. März in ihren Katalog ausgenutzter Sicherheitslücken aufgenommen. CERT-EU veröffentlichte am 25. März ein Advisory und verwies auf Maßnahmen aus der ToolShell-Angriffskampagne des Vorjahres. Der CVSS-Score liegt bei 9.8 von 10 und wurde hochgestuft, nachdem sich herausstellte, dass eine Ausnutzung auch ohne Authentifizierung möglich ist.
Parallel dazu hat CERT-Bund am 24. März Alarm wegen zweier Schwachstellen in Citrix NetScaler ADC und NetScaler Gateway geschlagen. CVE-2026-3055 ermöglicht es nicht authentifizierten Angreifern, aktive Session-Token aus dem Speicher betroffener Geräte auszulesen. CVE-2026-4368 kann durch eine Race Condition zur Übernahme fremder Benutzersitzungen führen. Besonders gefährdet sind Systeme, die als SAML Identity Provider konfiguriert sind, also eine in Unternehmensumgebungen weit verbreitete Konfiguration für Single Sign-On. Sicherheitsforscher bewerten eine baldige aktive Ausnutzung als sehr wahrscheinlich.
Sofortmaßnahmen: SharePoint patchen, NetScaler aktualisieren und aktiven Sessions beenden.
