Title
OpenBao's Namespace Deletion May Not Delete Data Properly
Summary
OpenBao is an open source identity-based secrets management system. Prior to 2.5.3, when OpenBao's initial namespace deletion fails, subsequent retries fail to properly remove all data before marking the namespace as deleted. This can affect any outstanding leases as well as potentially leaving unrelated storage entries around. This vulnerability is fixed in 2.5.3.

Title
ArgoCD ServerSideDiff is vulnerable to Kubernetes Secret Extraction
Summary
Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. From versions 3.2.0 to before 3.2.11 and 3.3.0 to before 3.3.9, there is a missing authorization and data-masking gap in Argo CD's ServerSideDiff endpoint that allows an attacker with read-only access to extract plaintext Kubernetes Secret data from etcd via the Kubernetes API server's Server-Side Apply dry-run mechanism. This issue has been patched in versions 3.2.11 and 3.3.9.

Title
OpenClaw < 2026.4.14 - Redaction Bypass via sourceConfig and runtimeConfig Aliases
Summary
OpenClaw before 2026.4.14 contains a redaction bypass vulnerability that allows authenticated gateway clients to receive unredacted secrets through sourceConfig and runtimeConfig alias fields. Attackers with config read access can exploit this to obtain provider API keys, gateway authentication material, and channel credentials that should have been redacted.

CVE-2026-45046 (GCVE-0-2026-45046)

Title
Gryph Agents Payload Filter Fails to Strip Tool Payload for Sensitive Content
Summary
Gryph provides a security layer for AI coding agents. Prior to 0.7.0, Gryph implements logging levels that determine what content is logged to a local sqlite database. The README incorrectly mentions that the default log level is minimal while it is standard. Source code review shows sensitive file-write content remains in the stored payload as ContentPreview, OldString, or NewString at the default standard logging level and at full. This leads to logging of potentially sensitive file content in the local sqlite database, violating Gryphs sensitive file filter and log level contracts. This vulnerability is fixed in 0.7.0.

Mitigation

Phase: Requirements

Description:

  • Clearly specify which information should be regarded as private or sensitive, and require that the product offers functionality that allows the user to cleanse the sensitive information from the resource before it is published or exported to other parties.
Mitigation ID: MIT-46

Phase: Architecture and Design

Strategy: Separation of Privilege

Description:

  • Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
  • Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
Mitigation ID: MIT-57

Phases: Implementation, Operation

Strategy: Attack Surface Reduction

Description:

  • Some tools can automatically analyze documents to redact, strip, or "sanitize" private information, although some human review might be necessary. Tools may vary in terms of which document formats can be processed.
  • When calling an external program to automatically generate or convert documents, invoke the program with any available options that avoid generating sensitive metadata. Some formats have well-defined fields that could contain private data, such as Exchangeable image file format (Exif), which can contain potentially sensitive metadata such as geolocation, date, and time [REF-1515] [REF-1516].
Mitigation ID: MIT-33

Phase: Implementation

Strategy: Attack Surface Reduction

Description:

  • Use naming conventions and strong types to make it easier to spot when sensitive data is being used. When creating structures, objects, or other complex entities, separate the sensitive and non-sensitive data as much as possible.
Mitigation

Phase: Implementation

Description:

  • Avoid errors related to improper resource shutdown or release (CWE-404), which may leave the sensitive data within the resource if it is in an incomplete state.
CAPEC-168: Windows ::DATA Alternate Data Stream

An attacker exploits the functionality of Microsoft NTFS Alternate Data Streams (ADS) to undermine system security. ADS allows multiple "files" to be stored in one directory entry referenced as filename:streamname. One or more alternate data streams may be stored in any file or directory. Normal Microsoft utilities do not show the presence of an ADS stream attached to a file. The additional space for the ADS is not recorded in the displayed file size. The additional space for ADS is accounted for in the used space on the volume. An ADS can be any type of file. ADS are copied by standard Microsoft utilities between NTFS volumes. ADS can be used by an attacker or intruder to hide tools, scripts, and data from detection by normal system utilities. Many anti-virus programs do not check for or scan ADS. Windows Vista does have a switch (-R) on the command line DIR command that will display alternate streams.
