CVE-2026-22190
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 · uneditedThe egg-mkfont utility in Panda3D versions up to and including 1.10.16 contains an uncontrolled format string vulnerability. The -gp (glyph pattern) command-line option is used directly as the format string for sprintf() with only a single argument supplied. If an attacker provides additional format specifiers, egg-mkfont may read unintended stack values and write the formatted output into generated .egg and .png files, resulting in disclosure of stack-resident memory and pointer values.
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.

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.
dbcve · scopedPanda3D 1.10.17 or later
- Identify all systems running Panda3D version 1.10.16 or earlier that use the egg-mkfont utility
- Download or access Panda3D version 1.10.17 or later from the official Panda3D repository (github.com/panda3d/panda3d)
- Backup any existing .egg files or font configuration files generated by egg-mkfont before upgrading
- Install the updated Panda3D version following the official installation instructions for your platform
- Test the -gp (glyph pattern) option with the new version to confirm the vulnerability is remediated
- Regenerate any previously created .egg and .png font files using the patched egg-mkfont utility
