HashBrown CMS through 1.4.6 contains an OS Command Injection vulnerability (CWE-78) in the media upload thumbnail generation routine. Media.generateThumbnail in src/Server/Entity/Resource/Media.js builds a temporary file path as 'thumbnail' + Path.extname(filename) and passes it, unescaped, into a shell command executed via AppService.exec ('convert ' + tempFile + ...).
CVE-2026-66902 is a critical OS command injection vulnerability in Google::Auth for Perl versions before 0.06. The vulnerability arises because the Pluggable subclass executes a command specified in an external_account credentials JSON file without proper validation or gating. This command is run via a system call that passes the entire string to the shell, allowing arbitrary command execution with the privileges of the application process. The vulnerability is reachable through the standard Application Default Credentials flow when the configuration includes credential_source.executable. No patch or official remediation guidance is currently available.
CVE-2026-16793 is a high-severity vulnerability in Lenovo XClarity Orchestrator 2.2.0 where improper neutralization of special elements in OS commands allows an authenticated attacker to execute arbitrary commands with privileged user rights. This vulnerability does not require user interaction and affects confidentiality, integrity, and availability. No patch or official remediation has been confirmed yet.
A post-authentication command injection vulnerability in the "export-cgi" CGI program in Zyxel WAX650S firmware versions through 7.10(ABRM.4)C0 could allow an authenticated attacker with administrator privileges to execute OS commands on an affected device.
Telenia Software TVox versions 26.5.3 and earlier 26.x, as well as 24.9.21 and earlier 24.x versions, contain an OS command injection vulnerability in the action_audio.php script. Authenticated attackers can exploit this flaw by passing a crafted pid parameter when the action parameter is set to checkProcess, allowing execution of arbitrary OS commands with apache user privileges.
An OS command injection vulnerability exists in the VPN module of TP-Link AXE75 V1 routers. This vulnerability allows an adjacent, authenticated attacker to execute arbitrary commands on the device by importing a specially crafted VPN client configuration file. The issue arises from improper filtering of special characters.
Successful exploitation of this vulnerability may enable an attacker to gain full control of the affected device, potentially compromising configuration integrity, network security, and service availability.
pgAdmin 4's Import/Export Data tool builds a psql \copy (...) command line by interpolating a user-supplied SQL query into a Jinja template and passing the rendered line to psql via --command. To stop an attacker from breaking out of the (...) wrapper, create_import_export_job() (route POST /import_export/job/<sid>, gated only by the ordinary, commonly-granted tools_import_export_data permission) validated the query with a hand-written parenthesis-balance checker, _is_query_parens_balanced(). That checker always treated a backslash before a single quote (\') as escaping the quote, i.e. as if standard_conforming_strings were off. PostgreSQL has defaulted standard_conforming_strings to on since 9.1 (2010), the default on every PostgreSQL version pgAdmin 4 currently supports (13-18); under that default psql's own \copy tokenizer treats \ as an ordinary character, so a single quote immediately after it closes the string literal. A query such as SELECT 'a\') TO PROGRAM 'echo pwned' x' was therefore accepted as "balanced" by pgAdmin's checker (which believed the ) was still inside the string), while psql, run through the actual rendered command line, closes the string at that point and treats the following ) as the end of the wrapping \copy (...) subquery, exposing an attacker-chosen TO PROGRAM '<command>' clause that psql executes via popen() -- independent of a subsequent syntax error later on the same line. This is the same class of bug as CVE-2025-12762/CVE-2025-13780 (RCE via psql meta-command/COPY injection during PLAIN-format dump restore), reached through an independently written defense in a different module (Import/Export Data rather than Restore) that had its own, different logic bug (inverted backslash-escape semantics rather than a BOM-defeated regex anchor).
The fix rejects any backslash inside a single-quoted string in the query outright, rather than picking one of the two possible psql interpretations. This is intentionally conservative: because the correct interpretation of \ depends on the target server's standard_conforming_strings setting, which the checker cannot reliably know at validation time, refusing the query is safer than guessing.
This issue affects pgAdmin 4: from the introduction of _is_query_parens_balanced() before 9.18.
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.
IBM HMC V10.3.1050.0 through 10.3.1064.0 and IBM HMC V11.1.1110.0 through 11.1.1112.0 Management systems in IBM Power environments (HMC and Novalink) could allow an unauthenticated user to execute arbitrary commands with elevated privileges on the system due to improper validation of user supplied input.
IBM Langflow OSS 1.0.0 through 1.10.1 are vulnerable to unauthenticated remote code execution via environment variable injection in the MCP (Model Context Protocol) stdio launcher. The vulnerability exists in src/lfx/src/lfx/base/mcp/util.py where the DANGEROUS_ENV_VARS blocklist fails to include SHELLOPTS , BASHOPTS , and PS4 environment variables.
