Title
VaahCMS 2.0.0 - 2.3.4 Malicious JavaScript Supply Chain via security-otp.blade.php
Summary
VaahCMS versions 2.0.0 through 2.3.4 contain a malicious obfuscated JavaScript payload embedded in the Blade template responsible for rendering security OTP emails, allowing remote attackers to execute unauthorized code in any browser that renders the affected email template with JavaScript enabled. The payload establishes a WebSocket connection to a hardcoded command-and-control endpoint, installs a password-field keylogger using MutationObserver to capture dynamically added inputs, scrapes WhatsApp Web DOM content, and accepts remote commands to redirect or overwrite the rendered page.

Title
ENDLESSDOORS: Zbtlink Router rctl/kworker Phone-Home Root Implant
Summary
Zbtlink router firmware ships an embedded remote-control implant, ENDLESSDOORS, present in every published build across the product line. It is the open-source ycsunjane/rctl tool built in as an OpenWrt package (librctl.so), started at boot and run as root under the process name kworker to blend in with the kernel's [kworker/*] threads. It opens no listening port; it phones home over cleartext TCP to a hardcoded command-and-control server (command channel 7000, interactive-shell callback 7001) with no authentication and no transport encryption, re-attempting contact roughly every 35 seconds. Its command handler passes any received string to popen() as uid=0, and a reserved rctlbash command returns an interactive root shell. Because the channel is unauthenticated and cleartext, control is not limited to whoever planted it: any party that answers at the C2 address, occupies the network path (DNS or route hijack), or acquires the hardcoded fallback domain obtains unauthenticated remote code execution as root.

Title
Supply chain compromise via malicious package versions (@cap-js/sqlite, @cap-js/postgres, @cap-js/db-service)
Summary
The SAP Cloud Application Programming Model is a tool for building enterprise-grade cloud applications, and cap-js/cds-dbs is the monorepo for SQL database services for that tool. On April 29, 2026, compromised versions of `@cap-js/sqlite@2.2.2`, `@cap-js/postgres@2.2.2`, and `@cap-js/db-service@2.10.1` were published. The malicious packages harvested credentials and attempted self-propagation. If a compromised version was installed, all credentials accessible on that machine (npm tokens, cloud provider credentials, SSH keys, GitHub PATs) should be considered compromised. User should upgrade to `@cap-js/sqlite` >= 2.4.0, `@cap-js/postgres` >= 2.3.0, `@cap-js/db-service` >= 2.11.0. If a compromised version was ever installed, rotate all affected credentials. No known workarounds are available.

Title
Malicious code in @beproduct/nestjs-auth (0.1.2 through 0.1.19) — Mini Shai-Hulud worm
Summary
@beproduct/nestjs-auth is a NestJS authentication module for BeProduct IDS (Identity Server) with OpenID Connect support. Between 2026-05-11 20:19 UTC and 22:56 UTC, an attacker used a compromised npm publish token to publish 18 malicious versions of `@beproduct/nestjs-auth` (0.1.2 through 0.1.19). The postinstall payload attempted to harvest npm tokens (from `~/.npmrc`); GitHub personal access tokens, OAuth tokens (`gho_*`), and Actions OIDC tokens; AWS credentials (from environment variables and `~/.aws/credentials`); HashiCorp Vault tokens; and other secrets present in environment variables. Version `0.1.20` is a clean republish from the original `0.1.1` source tree. Anyone who installed any version in the range `>=0.1.2 <=0.1.19` should remove the package and clean the npm cache; install the clean version; rotate every credential present in the install environment, including all npm publish tokens, all GitHub PATs and OAuth tokens, AWS access keys, HashiCorp Vault tokens, and any other secret that was in env vars or config files at install time; scan affected hosts for indicators of compromise and, if any are found, treat the host as compromised and reimage; and check committed repository history for unexpected additions in `.claude/` or `.vscode/` directories. The worm is known to commit `setup.mjs` + hook configs to PR branches via automated agent runtimes.

CVE-2026-45758 (GCVE-0-2026-45758)

Title
Malicious code in guardrails-ai 0.10.1 (supply chain compromise)
Summary
Guardrails AI is a Python framework that helps build AI applications. On May 11, 2026 at approximately 6:00 PM Pacific, an attacker published a malicious version of `guardrails-ai` (0.10.1) to PyPI. Aany user who installed `guardrails-ai==0.10.1` from PyPI on May 11, 2026 may be affected. Security researchers identified the malicious package within approximately 2 hours of publication, and PyPI quarantined the repository. Based on our telemetry, Guardrails AI maintainers have observed no requests to Guardrails AI infrastructure originating from the malicious 0.10.1 version, and a review of system and access logs has produced no evidence of user data exfiltration through their systems. Users should upgrade to version 0.10.2 or downgrade to version 0.10.0, both of which are unaffected. Those who installed version 0.10.1 should rotate any credentials accessible from their machine (GitHub PATs, cloud provider keys, package registry tokens, API keys) and audit their GitHub account for unauthorized workflows or repositories.

CVE-2026-45321 (GCVE-0-2026-45321)

Title
Malware in 42 @tanstack/* packages exfiltrates cloud credentials, GitHub tokens, and SSH keys
Summary
On 2026-05-11, between approximately 19:20 and 19:26 UTC, 84 malicious versions across 42 @tanstack/* packages were published to the npm registry. The publishes were authenticated via the legitimate GitHub Actions OIDC trusted-publisher binding for TanStack/router, but the publish workflow itself was not modified. The attacker chained three known vulnerability classes — a pull_request_target "Pwn Request" misconfiguration, GitHub Actions cache poisoning across the fork↔base trust boundary, and runtime memory extraction of the OIDC token from the Actions runner process — to publish credential-stealing malware under a trusted identity. Each affected package received exactly two malicious versions, published a few minutes apart.

Title
Smart Slider 3 Pro 3.5.1.35 Supply Chain Attack Remote Access Toolkit
Summary
Smart Slider 3 Pro version 3.5.1.35 for WordPress and Joomla contains a multi-stage remote access toolkit injected through a compromised update system that allows unauthenticated attackers to execute arbitrary code and commands. Attackers can trigger pre-authentication remote shell execution via HTTP headers, establish authenticated backdoors accepting arbitrary PHP code or OS commands, create hidden administrator accounts, exfiltrate credentials and access keys, and maintain persistence through multiple injection points including must-use plugins and core file modifications.

Mitigation
Implementation Operation

Remove the malicious code and start an effort to ensure that no more malicious code exists. This may require a detailed review of all code, as it is possible to hide a serious attack in only one or two lines of code. These lines may be located almost anywhere in an application and may have been intentionally obfuscated by the attacker.

CAPEC-442: Infected Software

An adversary adds malicious logic, often in the form of a computer virus, to otherwise benign software. This logic is often hidden from the user of the software and works behind the scenes to achieve negative impacts. Many times, the malicious logic is inserted into empty space between legitimate code, and is then called when the software is executed. This pattern of attack focuses on software already fielded and used in operation as opposed to software that is still under development and part of the supply chain.

CAPEC-448: Embed Virus into DLL

An adversary tampers with a DLL and embeds a computer virus into gaps between legitimate machine instructions. These gaps may be the result of compiler optimizations that pad memory blocks for performance gains. The embedded virus then attempts to infect any machine which interfaces with the product, and possibly steal private data or eavesdrop.

CAPEC-636: Hiding Malicious Data or Code within Files

Files on various operating systems can have a complex format which allows for the storage of other data, in addition to its contents. Often this is metadata about the file, such as a cached thumbnail for an image file. Unless utilities are invoked in a particular way, this data is not visible during the normal use of the file. It is possible for an attacker to store malicious data or code using these facilities, which would be difficult to discover.
