Summary

CVE-2025-47777 is a critical-severity Improper Input Validation (CWE-20) vulnerability in 5Ire 5Ire. Its CVSS base score is 9.6 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Browser Session Hijacking (T1185); ranked in the top 44% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

This vulnerability is AI-related — categorised as LLM Application Platforms; in the LLM/Generative AI Risks risk domain.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

5ire is a cross-platform desktop AI assistant and model context protocol client that is affected by a stored cross-site scripting vulnerability in versions prior to 0.11.1. The flaw stems from insufficient sanitization of chatbot responses, which can be escalated to remote code execution through unsafe Electron protocol handling and exposed APIs. The issue carries a CVSS score of 9.6 and is associated with CWE-20 and CWE-79.

An attacker can exploit the vulnerability by delivering malicious content through untrusted chatbots or externally pasted material, enabling arbitrary code execution on the victim's machine when the response is rendered. All users of affected 5ire clients are potentially impacted, with the attack requiring user interaction such as viewing the crafted response.

The project's GitHub security advisory and associated commit confirm that version 0.11.1 contains a fix. Linked references highlight Electron security guidance and prior research on URL-handling RCE vectors in similar applications, underscoring the need to apply the patch and follow recommended hardening practices for Electron-based clients.

The EPSS score remains low and unchanged at 0.0222 with no observed rise after disclosure.

Vulnerability Data

5ire is a cross-platform desktop artificial intelligence assistant and model context protocol client. Versions prior to 0.11.1 are vulnerable to stored cross-site scripting in chatbot responses due to insufficient sanitization. This, in turn, can lead to Remote Code Execution (RCE)…

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation can discover missing input validation through analysis or test cases.

SI-10 directly requires validity checks on information inputs, structurally preventing improper or missing validation.

Output filtering can catch or sanitize unneutralized script content before it is served to users.

Requiring documented development standards and tools can embed input-validation practices into the engineering process.

finds

Testing against a defined set of requirements and using code review plus vulnerability scanning forces validation of inputs and handling of unanticipated conditions, reducing the chance that malformed data will be accepted.

prevents

Knowledge exchange on emerging attack techniques and patches reduces the likelihood that cross-site scripting flaws remain unaddressed in deployed applications.

prevents

Operational indicators of compromise for web-application attacks can be incorporated into WAF or input-filtering rules, lowering the likelihood that unsanitized data reaches the browser.

prevents

Secure-coding guidelines and mandatory security testing (including code scans) compel developers to validate and sanitize inputs at design and implementation time, lowering the incidence of malformed or malicious data reaching downstream components.

prevents

Mandating input controls that include integrity checks and input validation ensures that untrusted data is examined before use, blocking the root cause of many injection and malformed-data weaknesses.

prevents

Security-by-design principles explicitly call for data validation and sanitization at every layer, reducing the chance that malformed or malicious input will be processed without scrutiny.
