Dromara Skyeye through commit 003549ae5615bd114ba5bb8ddf6a8e8ead97c321 contains an OS command injection vulnerability in the unauthenticated /post/TtsController/textToSpeech endpoint via the format parameter. Attackers can inject a single quote into format to break out of the PowerShell string and execute commands as the Skyeye service account on Windows.

AnalysisAI
Unauthenticated OS command injection in Dromara Skyeye allows remote attackers to execute arbitrary commands as the Skyeye service account on Windows. The flaw resides in the TTS textToSpeech endpoint, where the 'format' parameter is concatenated into a PowerShell string without sanitization; a single quote can break out and run attacker-supplied commands. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the Skyeye instance be running on Windows, because the injection breaks out of a PowerShell string constructed in the text-to-speech routine (TtsServiceImpl); the vulnerable code path is the /post/TtsController/textToSpeech endpoint with the attacker-controlled 'format' parameter. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | All available signals point to a genuinely high-priority, pre-authentication remote code execution issue. … 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; the CVE references a specific commit but no fixed version is provided. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory every Dromara Skyeye instance in the environment, flag those hosted on Windows, and determine which are reachable from untrusted networks or the internet; immediately block external and lateral access to the TTS textToSpeech endpoint at the WAF, reverse proxy, or firewall layer (deny requests to that path except from a tightly scoped administrative allowlist) and, where the instance is not business-critical, take it offline until mitigations are in place. …
