CVE-2026-1226
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 · uneditedCWE‑94: Improper Control of Generation of Code vulnerability exists that could cause execution of untrusted or unintended code within the application when maliciously crafted design content is processed through a TGML graphics file.
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 CWE-94 code injection vulnerability exists in TGML graphics file processing where maliciously crafted design content can cause the application to execute untrusted or unintended code. The improper control of code generation allows attackers to inject malicious code through the TGML file parsing mechanism.

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 TGML processing in your environmentSearch for applications, libraries, or modules that handle TGML graphics files. Use file system searches for .tgml file extensions or grep for TGML-related components in installed software listings and dependency manifests.Affected if TGML graphics file processing capability exists in your environment
-
Determine TGML parser versionLocate the version of the TGML processing component through application manifests, dependency lists, package managers, or library inventories. Compare this version against any available version information from your vendor.Affected if The TGML parser version cannot be verified or is not patched
-
Check for dynamic code generation featureExamine TGML parser configuration files, settings, or source code for features that enable dynamic code generation, eval(), Function constructor usage, or other unsafe code execution mechanisms during file parsing.Affected if Dynamic code generation or unsafe evaluation is enabled in TGML processing settings
-
Inspect TGML input validation implementationReview application code or configuration that handles TGML file input. Look for presence or absence of strict input validation, sanitization routines, and whitelist-based filtering applied to TGML file content before processing.Affected if No structured input validation or sanitization is implemented for TGML file content
You are affected if your environment processes TGML graphics files and the TGML parser has dynamic code generation enabled without proper input validation and sanitization for file content.
Generated from the published advisory. Verify against your own configuration.
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 dataImplement strict input validation and sanitization for TGML graphics files, avoiding dynamic code generation or unsafe evaluation practices. Use parameterized parsing and whitelist-based validation to ensure only intended design content is processed.
