Executive Summary

CVE-2026-54323 is a vulnerability in the Daytona software (versions up to 0.184.0) where the git clone operation disabled TLS certificate verification. This means that when the daemon cloned a git repository using credentials, it sent those credentials over a connection whose TLS certificate was not validated.

Because of this, an attacker who could intercept the network traffic (for example, via man-in-the-middle attacks, DNS poisoning, or controlled proxies) could present any TLS certificate, capture the Git credentials sent during the clone, and potentially serve tampered repository content into the sandbox.

This vulnerability was fixed in version 0.185.0 by enforcing TLS certificate verification during git clone operations.

Impact Analysis

This vulnerability can lead to the exposure of your Git credentials, such as personal access tokens or passwords, if you perform git clone operations using Daytona on untrusted networks.

An attacker intercepting your clone traffic could steal these credentials, which may grant them access not only to the cloned repository but also to other repositories you have access to on your Git provider.

Additionally, the attacker could serve tampered or malicious repository content into your sandbox environment, potentially compromising the integrity of your workflows.

Detection Guidance

To detect this vulnerability on your network or system, you should monitor git clone operations performed by the Daytona daemon versions prior to 0.185.0, especially those that include Git credentials sent over TLS connections without certificate verification.

One approach is to capture and analyze network traffic for git clone requests where the HTTP Basic Authorization header is sent over TLS connections that do not validate certificates. Tools like Wireshark or tcpdump can be used to capture this traffic.

• Use tcpdump to capture traffic on port 443 (HTTPS) and filter for git clone operations: sudo tcpdump -i any port 443 -w capture.pcap
• Analyze the capture with Wireshark to look for HTTP Basic Authorization headers sent during git clone requests over TLS connections without proper certificate validation.
• Check the version of Daytona daemon running on your system: daytona --version or check the installed package version to confirm if it is prior to 0.185.0.

Since the vulnerability involves improper TLS certificate validation, detecting unverified TLS connections during git clone operations is key.

Mitigation Strategies

The immediate mitigation step is to upgrade the Daytona daemon to version 0.185.0 or later, where TLS certificate verification is enforced by default during git clone operations.

If upgrading immediately is not possible, avoid supplying Git credentials during git clone operations over untrusted networks to prevent credential leakage.

Additionally, restrict git clone operations to trusted networks or use VPNs to secure the connection and prevent man-in-the-middle attacks.

Compliance Impact

This vulnerability allows an attacker to intercept Git credentials due to disabled TLS certificate verification during git clone operations. Such credential leakage can lead to unauthorized access to user repositories and potentially sensitive data.

The exposure of credentials and possible unauthorized access to repositories containing sensitive or personal data could result in non-compliance with data protection regulations such as GDPR and HIPAA, which require appropriate safeguards to protect personal and sensitive information.

Therefore, organizations using vulnerable versions of Daytona may face increased risk of data breaches and compliance violations until the vulnerability is patched or mitigated.
