Vulnerability from github – Published: 2021-08-25 20:42 – Updated: 2026-06-09 10:46

Summary

Multiple memory safety issues in actix-web

Details

Affected versions contain multiple memory safety issues, such as:

Unsoundly coercing immutable references to mutable references
Unsoundly extending lifetimes of strings
Adding the Send marker trait to objects that cannot be safely sent between threads

This may result in a variety of memory corruption scenarios, most likely use-after-free.

A signficant refactoring effort has been conducted to resolve these issues.

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
