Lifecycle Timeline
2DescriptionCVE.org
Quickwit through 0.9.0 fails to validate the host and scheme of the queue_url parameter in SQS file sources, allowing attackers to make the node issue requests to arbitrary internal addresses. Attackers can supply a malicious queue_url to the create-source API to scan internal networks and fingerprint services based on connection response differences.
AnalysisAI
Server-side request forgery in Quickwit through 0.9.0 allows remote attackers to coerce a Quickwit node into issuing HTTP requests to arbitrary internal addresses by supplying a crafted queue_url when creating an SQS file source. Because Quickwit ships without built-in authentication, any deployment whose management/create-source REST API is network-reachable is effectively unauthenticated against this attack; the only real prerequisite is that the SQS file source feature be usable and that a source definition containing an attacker-chosen queue_url can be POSTed. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires that the attacker can reach Quickwit's management/create-source REST API and that the SQS file source feature is usable - Quickwit ships without built-in authentication, so in a default deployment where the API is network-reachable this is unauthenticated. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals are moderate, not critical. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No vendor-released patch identified at time of analysis, so remediation depends on compensating controls until a fix version is confirmed via GitHub issue 6703 or the VulnCheck advisory. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all Quickwit deployments and confirm whether any instance at or below 0.9.0 has its management/create-source REST API reachable from untrusted networks; where it is, immediately restrict access to trusted administrative networks or a VPN via firewall or security-group rules, and disable the SQS file source feature on any instance that does not require it. …
