A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

AI-suggested

Since the vulnerability arises from missing authorization checks, remediation involves implementing proper access control verification to ensure that only conversation participants can access or modify conversation data. Until a fix is available, restrict access to authenticated users and monitor for suspicious activity related to conversation access.

Description

CVE-2026-106677 is an Insecure Direct Object Reference (IDOR) vulnerability in Homestay3 homestay-backend version 0.0.1-SNAPSHOT. It allows an authenticated user to access and manipulate conversations and messages for arbitrary conversation IDs without verifying if the user is a participant in those conversations.

Impact

An attacker with valid authentication credentials can access and manipulate conversations they are not authorized to participate in. This compromises confidentiality and integrity of chat messages, potentially exposing private communications and allowing unauthorized message sending or status changes.

Summary

The vulnerability exists in the ChatServiceImpl component of Homestay3 homestay-backend 0.0.1-SNAPSHOT. Due to lack of proper authorization checks, an authenticated user can view conversations, read messages, send messages, and mark messages as read for any conversation ID, regardless of participation. This is a classic IDOR flaw where access control is insufficient, enabling unauthorized access to potentially sensitive communication data.
