CVE-2026-25208
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedInteger overflow vulnerability in Samsung Open Source Escargot allows Overflow Buffers.This issue affects Escargot: 97e8115ab1110bc502b4b5e4a0c689a71520d335.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · low confidenceInteger overflow vulnerability in Samsung's Escargot JavaScript engine allows buffer overflows. The vulnerability stems from insufficient validation of integer values used in memory allocation or array indexing operations, potentially enabling an attacker to overwrite adjacent memory regions.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if Escargot JavaScript engine is in useSearch for escargot library files (escargot*.so, escargot*.dll, libescargot*) or check application dependencies that reference the Escargot engineAffected if Escargot library files or dependencies are found in the environment
-
Determine the installed Escargot versionQuery the application or library version - check via package manager (npm, yarn, etc.), file metadata, or run the application with a version flag if availableAffected if The version cannot be determined or returns the date-based version 2026-03-26
-
Compare installed version to affected rangeIf version is determined, verify whether it equals exactly 2026-03-26 - note that other date-based versions or build IDs may differAffected if The installed version is exactly 2026-03-26 (the only version listed as affected)
-
Confirm the integer overflow attack surface existsVerify that the application or context using Escargot processes untrusted or externally-sourced JavaScript code that could trigger memory allocation or array indexing operationsAffected if Untrusted JavaScript code execution is possible and the Escargot version is 2026-03-26
A user is affected if their environment contains Escargot version exactly 2026-03-26 and that engine processes JavaScript code that could trigger the vulnerable integer arithmetic operations.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply the patch for commit 97e8115ab1110bc502b4b5e4a0c689a71520d335 and ensure proper bounds checking is implemented for integer arithmetic operations that influence buffer sizes.
