Vikunja is an open-source self-hosted task management platform. Prior to 2.3.0, the OIDC callback handler issues a full JWT token without checking whether the matched user has TOTP two-factor authentication enabled. When a local user with TOTP enrolled is matched via the OIDC email fallback mechanism, the second factor is completely skipped. This vulnerability is fixed in 2.3.0.

OpenClaw before 2026.3.22 contains an unvalidated WebView JavascriptInterface vulnerability allowing attackers to inject arbitrary instructions. Untrusted pages can invoke the canvas bridge to execute malicious code within the Android application context.

OpenClaw before 2026.3.2 contains a filesystem boundary bypass vulnerability in the image tool that fails to honor tools.fs.workspaceOnly restrictions. Attackers can traverse sandbox bridge mounts outside the workspace to read files that other filesystem tools would reject.

OpenClaw before 2026.3.24 contains an arbitrary code execution vulnerability in local plugin and hook installation that allows attackers to execute malicious code by crafting a .npmrc file with a git executable override. During npm install execution in the staged package directory, attackers can leverage git dependencies to trigger execution of arbitrary programs specified in the attacker-controlled .npmrc configuration file.

In systemd 259, systemd-journald can send ANSI escape sequences to the terminals of arbitrary users when a "logger -p emerg" command is executed, if ForwardToWall=yes is set.

Step CA is an online certificate authority for secure, automated certificate management for DevOps. From 0.24.0 to before 0.30.0-rc3, an attacker can trigger an index out-of-bounds panic in Step CA by sending a crafted attestation key (AK) certificate with an empty Extended Key Usage (EKU) extension during TPM device attestation. When processing a device-attest-01 ACME challenge using TPM attestation, Step CA validates that the AK certificate contains the tcg-kp-AIKCertificate Extended Key Usage OID. During this validation, the EKU extension value is decoded from its ASN.1 representation and the first element is checked. A crafted certificate could include an EKU extension that decodes to an empty sequence, causing the code to panic when accessing the first element of the empty slice. This vulnerability is only reachable when a device-attest-01 ACME challenge with TPM attestation is configured. Deployments not using TPM device attestation are not affected. This vulnerability is fixed in 0.30.0-rc3.

In systemd 258 before 260, a local unprivileged user can trigger an assert when a Delegate=yes and User=<unset> unit exists and is running.

TREK is a collaborative travel planner. Prior to 2.7.2, TREK served uploaded photos without requiring authentication. This vulnerability is fixed in 2.7.2.

OpenClaw before 2026.3.25 contains a privilege escalation vulnerability in the gateway plugin subagent fallback deleteSession function that uses a synthetic operator.admin runtime scope. Attackers can exploit this by triggering session deletion without a request-scoped client to execute privileged operations with unintended administrative scope.

A stack buffer overflow exists in wolfSSL's PKCS7 implementation in the wc_PKCS7_DecryptOri() function in wolfcrypt/src/pkcs7.c. When processing a CMS EnvelopedData message containing an OtherRecipientInfo (ORI) recipient, the function copies an ASN.1-parsed OID into a fixed 32-byte stack buffer (oriOID[MAX_OID_SZ]) via XMEMCPY without first validating that the parsed OID length does not exceed MAX_OID_SZ. A crafted CMS EnvelopedData message with an ORI recipient containing an OID longer than 32 bytes triggers a stack buffer overflow. Exploitation requires the library to be built with --enable-pkcs7 (disabled by default) and the application to have registered an ORI decrypt callback via wc_PKCS7_SetOriDecryptCb().
