The CVE-2025-XXXXX vulnerability in `handcraftedinthealps/goodby-csv` involves a gadget chain that could enable remote code execution (RCE) under specific conditions. This occurs when untrusted data is deserialized in an insecure manner within an application. The library itself does not directly expose a vulnerability but provides a method chain (CallbackCollection.php) that, when combined with insecure deserialization, can lead to RCE. Attackers must exploit another flaw to inject malicious serialized data, which then leverages goodby-csv‘s gadget chain to execute arbitrary code.
DailyCVE Form:
Platform: GitHub
Version: <1.4.3
Vulnerability: Gadget Chain RCE
Severity: Low
Date: Jun 13, 2025
Prediction: Patch expected by Jun 20, 2025
What Undercode Say:
Check if goodby-csv is installed (Composer) composer show handcraftedinthealps/goodby-csv Upgrade to patched version composer require handcraftedinthealps/goodby-csv:1.4.3
How Exploit:
- Requires insecure deserialization in parent app.
- Malicious payload triggers gadget chain.
- Executes arbitrary code via
CallbackCollection.php.
Protection from this CVE:
- Upgrade to v1.4.3.
- Disable unsafe deserialization.
- Use allow-listed classes.
Impact:
- Low direct risk.
- Critical if chained.
- No known exploits.
