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-2026-42880 (GCVE-0-2026-42880)

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.

CVE-2026-42186 (GCVE-0-2026-42186)

Vulnerability from cvelistv5 – Published: 2026-05-14 14:36 – Updated: 2026-05-14 15:36

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.

CVE-2026-32891 (GCVE-0-2026-32891)

Title
Anchorr Privilege Escalation: Jellyseerr User → Anchorr Admin via Stored XSS
Summary
Anchorr is a Discord bot for requesting movies and TV shows and receiving notifications when items are added to a media server. Versions 1.4.1 and below contain a stored XSS vulnerability in the Jellyseerr user selector. Jellyseerr allows any account holder to execute arbitrary JavaScript in the Anchorr admin's browser session. The injected script calls the authenticated /api/config endpoint - which returns the full application configuration in plaintext. This allows the attacker to forge a valid Anchorr session token and gain full admin access to the dashboard with no knowledge of the admin password. The same response also exposes the API keys and tokens for every integrated service, resulting in simultaneous account takeover of the Jellyfin media server (via JELLYFIN_API_KEY), the Jellyseerr request manager (via JELLYSEERR_API_KEY), and the Discord bot (via DISCORD_TOKEN). This issue has been fixed in version 1.4.2.

Jellyseerr allows any account holder to execute arbitrary JavaScript in the Anchorr admin\u0027s browser session. The injected script calls the authenticated /api/config endpoint - which returns the full application configuration in plaintext. This allows the attacker to forge a valid Anchorr session token and gain full admin access to the dashboard with no knowledge of the admin password. The same response also exposes the API keys and tokens for every integrated service, resulting in simultaneous account takeover of the Jellyfin media server (via JELLYFIN_API_KEY), the Jellyseerr request manager (via JELLYSEERR_API_KEY), and the Discord bot (via DISCORD_TOKEN).

Title
FacturaScripts: Unstripped Image Metadata (EXIF) Leakage via Library Module File Upload/Download
Summary
FacturaScripts is an open source accounting and invoicing software. In versions prior to 2026, the Library module stores and serves uploaded images byte-for-byte, without stripping EXIF/XMP/IPTC metadata. Any authenticated user who downloaded an image could extract the uploader's embedded metadata, which included GPS coordinates, device information, timestamps, embedded comments/notes, thumbnail previews, and other personally identifiable information (PII) preserved in the image metadata. Of all FacturaScripts' image upload features, only the Library module combined unrestricted uploads, persistent storage, authenticated download access, and a total lack of server-side metadata sanitization. This vulnerability carries significant real-world impact: an employee uploading a photo taken at their home inadvertently discloses their precise home address to every user with Library download access. This issue has been fixed in version 2026.

Title
tfplan2md has Sensitive Value Exposure in Generated Reports
Summary
tfplan2md is software for converting Terraform plan JSON files into human-readable Markdown reports. Prior to version 1.26.1, a bug in tfplan2md affected several distinct rendering paths: AzApi resource body properties, AzureDevOps variable groups, Scriban template context variables, and hierarchical sensitivity detection. This caused reports to render values that should have been masked as "(sensitive)" instead. This issue is fixed in v1.26.1. No known workarounds are available.

Mitigation
Requirements

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 MIT-46
Architecture and Design

Strategy: Separation of Privilege

  • 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 MIT-57
Implementation Operation

Strategy: Attack Surface Reduction

  • 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 MIT-33
Implementation

Strategy: Attack Surface Reduction

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
Implementation

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.
