xidown (a yt-dlp/ffmpeg GUI wrapper) builds its yt-dlp command-line invocation (xidown/core/scanner.py and downloader.py) by appending the user-provided or scanned URL as a bare trailing positional argument, with no '--' end-of-options marker and no scheme validation anywhere in the codebase. Because yt-dlp parses any argument beginning with '-' as a CLI option rather than link text, a crafted 'URL' value such as -U (yt-dlp's self-update flag) or --exec=... is parsed as a real yt-dlp option instead of a URL, altering the tool's control flow before its own URL validation runs. Full code execution via --exec was not demonstrated in the single-URL flow tested, but the underlying argument-injection primitive is confirmed and unmitigated across all call sites.

The MASTER_PASSWORD_HOOK setting, introduced in pgAdmin 4 7.2, lets an administrator configure an external command that returns a per-user encryption key, with %u in the configured string replaced by the current user's name. The previous implementation substituted the username directly into the command string and executed the result with subprocess.Popen(..., shell=True). Because the username can originate from an external authentication source (OAuth/OIDC claims, Kerberos, webserver auth) rather than a value pgAdmin fully controls, a username containing shell metacharacters (';', '$()', backticks, pipes, '&&', newlines) allowed an authenticated user to execute arbitrary commands as the pgAdmin service account in any deployment where the configured hook string uses %u. Fix tokenises the trusted, administrator-configured hook string into an argument vector first (using shlex in POSIX-quoting mode, with backslash-escaping disabled so Windows-style paths are not mis-parsed), substitutes the untrusted username into the individual argv elements, and executes with shell=False. The username is therefore always confined to a single argv element; any shell metacharacters it contains are inert. Administrators whose MASTER_PASSWORD_HOOK previously relied on shell features (pipes, redirection, environment-variable expansion, globbing) within the hook string itself must move that logic into the invoked script, since it is no longer interpreted by a shell. This issue affects pgAdmin 4: from 7.2 before 9.17.

Bulletin ID: 2026-065-AWS Scope: AWS Content Type: Important (requires attention) Publication Date: 07/23/2026 13:00 PM PDT Description: The AWS Bedrock AgentCore Python SDK (bedrock-agentcore) provides tools for building AI agents, including a Code Interpreter client that installs Python packages into a managed sandbox. We identified CVE-2026-16796, an improper neutralization of argument delimiters in the install_packages() method that might allow a remote authenticated user to execute arbitrary commands within the Code Interpreter sandbox via crafted package name arguments. Impacted versions: bedrock-agentcore version <1.18.1 Please refer to the article below for the most up-to-date and complete information related to this AWS Security Bulletin.

BuildKit custom frontends or clients using the raw low-level API can set git.checkoutbundle=true when checking out Git sources. If the Git source is malicious, this could lead to a crafted command invocation on the host.

Red Hat Ansible Automation Platform provides an enterprise framework for building, deploying and managing IT automation at scale. IT Managers can provide top-down guidelines on how automation is applied to individual teams, while automation developers retain the freedom to write tasks that leverage existing knowledge without the overhead. Ansible Automation Platform makes it possible for users across an organization to share, vet, and manage automation content by means of a simple, powerful, and agentless language. Security Fix(es): * ansible-core: argument injection in ansible-galaxy role install leads to arbitrary code execution (CVE-2026-11332) * receptor: golang.org/x/net/html: Cross-Site Scripting via HTML parsing bypass (CVE-2026-27136) * receptor: golang crypto/x509: Denial of Service via excessive processing of DNS SAN entries (CVE-2026-27145) * receptor: golang.org/x/net/idna: Privilege escalation via incorrect Punycode label processing (CVE-2026-39821) For details about this release, refer to the release notes listed in the References section.

dbt-mcp versions prior to 1.17.1 contain a vulnerability where unsanitized input is appended to subprocess arguments, allowing argument injection of dbt global flags. This flaw is fixed in version 1.17.1.

Repomix is a tool that packs repositories into AI-friendly files. Prior to 1.14.1, src/core/git/gitCommand.ts execGitShallowClone passes the --remote-branch value directly to git fetch and git checkout without validation or --end-of-options, allowing --upload-pack or other Git option injection that bypasses validateGitUrl() dangerous parameter checks and can execute commands through local or SSH-style transports. This issue is fixed in version 1.14.1.
