CVE-2026-25205
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 · uneditedHeap-based buffer overflow vulnerability in Samsung Open Source Escargot allows out-of-bounds write.This issue affects Escargot:commit hash 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 · moderate confidenceA heap-based buffer overflow vulnerability in Samsung's Escargot JavaScript engine allows an attacker to write data beyond the boundaries of allocated heap memory. This memory corruption occurs during JavaScript execution and can be triggered by maliciously crafted JavaScript code, potentially leading to arbitrary code execution. The vulnerability affects Escargot at specific commit hash 97e8115ab1110bc502b4b5e4a0c689a71520d335.

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 useInspect the application dependencies, libraries, or components to determine if the Escargot JavaScript engine is present or being usedAffected if Escargot is present in the environment and its version matches the affected build date or commit hash
-
Determine Escargot version or build dateCheck the version string, build metadata, or binary information for Escargot. This may be found in library manifests, version files, or runtime version APIs if exposedAffected if The version or build date is 2026-03-26
-
Check Escargot commit hashInspect the Escargot binary, source code metadata, or build artifacts for the Git commit hashAffected if The commit hash is 97e8115ab1110bc502b4b5e4a0c689a71520d335
-
Verify JavaScript execution is enabledDetermine whether the application or component exposes JavaScript execution capabilities to users or external inputAffected if JavaScript execution is enabled and untrusted code can be processed by Escargot
A user is affected if their environment uses Escargot JavaScript engine version 2026-03-26 (commit 97e8115ab1110bc502b4b5e4a0c689a71520d335) and JavaScript execution is enabled.

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 dataUpdate Escargot to the latest version containing the security patch. If an updated version is unavailable, implement sandboxing or disable JavaScript execution in affected components to reduce attack surface.
