postgresql: PostgreSQL: Arbitrary code execution via type confusion with "internal" arguments

A type confusion vulnerability in PostgreSQL allows any user to execute arbitrary code as the database's operating system user by calling functions with mishandled "internal" data type arguments...

postgresql: PostgreSQL pg_dump: Arbitrary code execution via crafted transform lists

A flaw was found in PostgreSQL pgdump. A heap buffer overflow vulnerability exists when processing long function transform lists. An authenticated object creator can exploit this by providing a specially crafted transform list. This allows the attacker to execute arbitrary code as the operating...

postgresql-fuzzystrmatch: PostgreSQL fuzzystrmatch: Arbitrary code execution via integer wraparound

A flaw was found in PostgreSQL fuzzystrmatch. A low-privileged database user can exploit an integer wraparound vulnerability by providing extreme inputs to the levenshtein or levenshteinlessequal SQL functions. This allows the user to execute arbitrary code as the operating system user running th...

postgresql: pltcl: plperl: PostgreSQL: Arbitrary code execution in 32-bit pltcl and plperl

A flaw was found in PostgreSQL. An integer wraparound vulnerability in 32-bit builds of pltcl and plperl allows an object creator to cause the server to undersize an allocation and write out-of-bounds via crafted function bodies. This can lead to arbitrary code execution as the operating system...

postgresql: PostgreSQL: Arbitrary code execution via type confusion in 'refint' module

A flaw was found in PostgreSQL. A type confusion vulnerability in the 'refint' module allows an object creator to execute arbitrary code as the operating system user running the database. This could lead to a complete compromise of the database server...

postgresql: PostgreSQL: Arbitrary code execution via heap buffer overflow in regexp

A flaw was found in PostgreSQL. A heap buffer overflow vulnerability exists in the regexp component, which can be triggered by a query author providing text that does not pass encoding validation. This can lead to unanticipated data growth, allowing the attacker to execute arbitrary code as the...

postgresql: PostgreSQL: Arbitrary code execution via plperl tied hash heap buffer overflow

A flaw was found in PostgreSQL. A heap buffer overflow vulnerability exists in the plperl component when returning a tied hash. This allows a function owner to execute arbitrary code as the operating system user running the database by providing a specially crafted function body. This could lead ...

USN-8852-1 openvpn vulnerabilities

It was discovered that OpenVPN had a use-after-free vulnerability in its TLS session handling. An attacker could possibly use this issue to cause OpenVPN to crash, resulting in a denial of service, or execute arbitrary code. CVE-2026-84471 It was discovered that OpenVPN incorrectly handled...

USN-8852-1: OpenVPN vulnerabilities

It was discovered that OpenVPN had a use-after-free vulnerability in its TLS session handling. An attacker could possibly use this issue to cause OpenVPN to crash, resulting in a denial of service, or execute arbitrary code. CVE-2026-84471 It was discovered that OpenVPN incorrectly handled...

CVE-2026-92957

A flaw was found in vm2. Untrusted code running within the sandbox can bypass module restriction policies to achieve arbitrary code execution on the underlying host. Due to improper normalization of module names containing the node: prefix, deny-list rules fail to prevent access to sensitive...

CVE-2026-92956

A flaw was found in vm2. When running untrusted code within a sandbox, improper isolation in WebAssembly streaming functions allows host error objects to leak into the sandbox environment. An attacker capable of running code inside the sandbox can exploit this flaw to escape sandbox containment a...

CVE-2026-92951

A flaw was found in vm2. The external package allowlist improperly validates package names using substring matching rather than exact name boundaries. An attacker capable of running code within the sandbox can exploit this issue by requesting a package name containing an allowlisted substring,...

CVE-2026-92950

A flaw was found in vm2. An attacker can achieve arbitrary code execution on the host system by escaping sandbox isolation through the command-line interface CLI tool. By supplying a malicious script that uses the require function to re-execute itself within the host environment, untrusted code c...

CVE-2026-92946

A flaw was found in vm2. This vulnerability allows an attacker executing untrusted code within the sandbox to escape isolation and achieve arbitrary code execution on the host system. When external module loading is permitted without restricting access to dependency directories, sandboxed code ca...

CVE-2026-92944

A flaw was found in vm2. An attacker capable of running code within the sandbox environment can bypass security wrappers by supplying a crafted asynchronous Promise object. This flaw allows the attacker to escape the sandbox and access host system objects, leading to arbitrary code execution on t...

CVE-2026-92939

A flaw was found in vm2. When the cryptographic built-in module is enabled, functions exposed to the sandbox continue to run with the privileges of the host process. An attacker capable of running untrusted code within the sandbox can invoke the crypto.setEngine function to load a malicious local...

CVE-2026-92938

A flaw was found in vm2. Untrusted code running within the sandbox environment can bypass isolation restrictions when the host SQLite module is accessible. By crafting module import requests and loading native database extensions, an attacker can escape the sandbox and achieve arbitrary code...

CVE-2026-92937

A flaw was found in vm2. This vulnerability allows an attacker to escape the sandbox environment and achieve arbitrary code execution on the host system. The issue occurs because the sandbox bridge fails to properly sanitize rejected Promise errors when handlers are registered through indirect...

CVE-2026-92934

A flaw was found in vm2. A remote attacker able to run code within the sandbox can bypass environment isolation by exploiting an error handling flaw that fails to properly sanitize host objects. By accessing these unprotected host objects, an attacker can achieve arbitrary code execution and acce...

CVE-2026-92935

A flaw was found in vm2. This vulnerability allows an attacker who can execute untrusted JavaScript inside the sandbox to achieve arbitrary code execution on the host system. By providing an array value to the require configuration when nested sandboxes are enabled, the attacker can bypass...
