The Sigma Forms Pro plugin for WordPress contains a critical Remote Code Execution vulnerability affecting all versions up to and including 1.4.5. The flaw exists in the handle_form_submission function, which dynamically grants the unfiltered_upload capability to all users during form submissions and bypasses MIME type validation when allowed_file_types is not configured. This allows unauthenticated attackers to upload arbitrary files and execute code on the server. The vulnerability is made immediately exploitable upon installation because several default pre-built templates, including Job Application, Support Ticket, and Wholesale Application, include file upload fields with no file type restrictions by design. The combination of privilege escalation, MIME bypass, and insecure defaults makes this a critical, zero-authentication attack vector requiring urgent patching.
Bekijk origineel advisory →Skyvern versions before 1.0.45 contain a critical sandbox escape vulnerability in the TextPromptBlock component. The flaw arises because prompts are rendered twice: first through a sandboxed Jinja environment and then through an unsandboxed one. This double-rendering allows attackers to inject malicious Jinja template syntax via workflow parameters or upstream block output. Successful exploitation enables arbitrary code execution with server process privileges. The vulnerability is tracked as CVE-2026-82447 and was patched in version 1.0.45. A fix was committed in commit d723de621d5b3a340f3cc4d5b46bfe40a9a3124e. Affected files include skyvern/forge/sdk/prompting.py and skyvern/forge/sdk/workflow/models/block.py.
Bekijk origineel advisory →pac4j-core versions before 6.5.6 contain a critical authentication bypass vulnerability in the CheckProfileTypeAuthorizer component. The flaw stems from reversed profile type validation logic, allowing attackers to authenticate using a weaker client and gain access to resources that require a stronger profile type. By satisfying generic profile checks, malicious actors can bypass intended access controls. The vulnerability has been patched in version 6.5.6. A security advisory has been published by the pac4j project, and a fix commit is available on GitHub. This issue affects any application relying on pac4j-core's CheckProfileTypeAuthorizer for enforcing profile-based authorization. Users are strongly advised to upgrade to version 6.5.6 or later to mitigate the risk.
Bekijk origineel advisory →On August 28, 2026, ten malicious versions of the npm package @7nohe/openapi-react-query-codegen were published in two waves as part of the Mini Shai-Hulud supply chain attack. A threat actor abused a comment-triggered GitHub Actions publishing workflow, allowing any GitHub account to publish fork code under the repository's trusted OIDC identity by simply commenting 'npm publish' on a pull request. All ten malicious versions carry valid npm provenance attestations, meaning npm audit signatures will not flag them. The malicious releases execute a bundled obfuscated JavaScript loader (3FWCvzduYZg.js) at install time, which decrypts an AES-128-GCM payload, writes it to a temp file, executes it, and deletes it. The latest tag still resolves to the malicious version 3.0.4 at time of writing. Users are advised to pin to known-good versions (0.5.3, 1.6.2, 2.2.0, or 3.0.2), clear caches, and treat any machine that installed an affected version as compromised. The threat actor's GitHub account (p00paboot) staged the malicious code via a fork of the repository.
