Improper Access Restriction of Internal Aggregation Expression in MongoDB Server Leads to Assertion Failure and Denial of Service

An internal aggregation expression in MongoDB Server was incorrectly registered as accessible to any authenticated user rather than being restricted to internal cluster operations. By crafting a malformed index specification within this expression, an authenticated user with read-only privileges...

CVE-2026-82059 Improper Access Restriction of Internal Aggregation Expression in MongoDB Server Leads to Assertion Failure and Denial of Service

An internal aggregation expression in MongoDB Server was incorrectly registered as accessible to any authenticated user rather than being restricted to internal cluster operations. By crafting a malformed index specification within this expression, an authenticated user with read-only privileges...

USN-8736-1 perl vulnerabilities

It was discovered that Perl incorrectly handled certain large inputs during regular expression matching. An attacker could possibly use this issue to trigger out-of-bounds heap reads or writes, resulting in a denial of service or arbitrary code execution. CVE-2026-15534 It was discovered that Per...

USN-8736-1: Perl vulnerabilities

It was discovered that Perl incorrectly handled certain large inputs during regular expression matching. An attacker could possibly use this issue to trigger out-of-bounds heap reads or writes, resulting in a denial of service or arbitrary code execution. CVE-2026-15534 It was discovered that Per...

PT-2026-88507

Impact The expression compiler's sanitizer resolved through a dynamically-scoped this, so a class field named sanitize rebound it and reached the Function constructor. On the backend, any expression author could run code in the n8n process; in the editor preview, a member's expression could run a...

CVE-2026-86083: Improper Control of Generation of Code

n8n is an open source workflow automation platform. Prior to 1.123.76, 2.37.7, and 2.38.2, the legacy expression engine generated source text by calling the mutable global JSON.stringify while printing synthetic string literals and interpolating timezone data. An expression could replace...

Improper input validation in the Vega expression function implementation in OpenSearch Dashboards allows a remote authenticated actor with dashboard write permissions to execute arbitrary JavaScript in the context of other users' browser sessions by saving a crafted Vega visualization. The...

CVE-2026-84942: Improper Neutralization of Input During Web Page Generation

Improper input validation in the Vega expression function implementation in OpenSearch Dashboards allows a remote authenticated actor with dashboard write permissions to execute arbitrary JavaScript in the context of other users' browser sessions by saving a crafted Vega visualization. The...

PT-2026-88499

Impact Two stages of expression code generation built source text by calling the global JSON.stringify at generation time: the compiler when printing synthetic string literals, and the isolate bridge when interpolating a timezone value into its per-evaluation wrapper. An expression that replaced...

Name of the Vulnerable Software and Affected Versions MongoDB Server affected versions not specified Description An internal aggregation expression was incorrectly registered as accessible to any authenticated user instead of being restricted to internal cluster operations. An authenticated user...

CVE-2026-86076: Improper Control of Generation of Code

n8n is an open source workflow automation platform. Prior to 1.123.76, 2.37.7, and 2.38.2, the expression compiler sanitizer resolved through dynamically scoped this and did not reject reserved class member names. A class field named sanitize could rebind the sanitizer and reach the Function...

CVE-2026-78626: Incorrect Authorization

The Okta Access Gateway improperly handles input sanitization and regular expression evaluation within its Protected Rule authorization check, resulting in an authorization bypass when an administrator has explicitly configured a Protected Rule policy on one or more application resources...

PT-2026-88512

Impact The Git node's clone operation matched the destination path against the default N8N BLOCK FILE PATTERNS expression, which was written so that a crafted path caused catastrophic backtracking. Evaluation runs synchronously in the main n8n process, so an authenticated user could freeze the...

PT-2026-95732

Summary @tiptap/core contains two quadratic regular-expression denial-of-service paths in its default Markdown attribute parsers. Pandoc-style block attributes use two unanchored greedy expressions that rescan repeated QUOTED 0 prefixes. Inline shortcode attributes use another unanchored greedy k...

CVE-2026-86142

A flaw in libxml2's xmlXPtrEvalXPtrPart function allows a local attacker to cause a heap-based buffer overflow. An integer overflow while processing an oversized xpointer expression leads to incorrect memory allocation and an out-of-bounds write, potentially resulting in information disclosure,...

ROS-20260907-73-0072

The vulnerability in python-pygments is related to the use of a regular expression c, which has an inefficient computational complexity. Exploiting this vulnerability may allow a remote attacker to cause a service failure...
