Lifecycle Timeline
4DescriptionCVE.org
A flaw has been found in jkawamoto mcp-florence2 up to 0.3.13. Affected by this issue is the function get_images of the file src/mcp_florence2/__init__.py. This manipulation of the argument src causes server-side request forgery. The attack may be initiated remotely. The exploit has been published and may be used. It is recommended to change the configuration settings. The vendor explains: "For deployments where SSRF protection is required, I recommend routing all HTTP(S) requests through an SSRF-safe proxy server. This approach mitigates the vulnerability without requiring changes to the mcp-florence2 source code."
AnalysisAI
Server-side request forgery in jkawamoto mcp-florence2 (all versions through 0.3.13) enables remote low-privilege attackers to manipulate the src argument of the get_images function, causing the server to issue arbitrary HTTP requests to attacker-controlled destinations - including internal network services and cloud metadata endpoints. A public proof-of-concept is available via GitHub issue #59, lowering the exploitation bar significantly. …

Vulnerability AssessmentAI
| Exploitation | The attacker must hold low-privilege authenticated access to the mcp-florence2 MCP server, as confirmed by the CVSS 4.0 PR:L metric - unauthenticated exploitation is not supported by the available data. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N) confirms network-accessible exploitation with low attack complexity and no special attack requirements, but PR:L constrains the attack surface to authenticated low-privilege users - unauthenticated mass exploitation is not supported by the available data. … 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 patched version of mcp-florence2 has been confirmed at the time of analysis - the vendor's own guidance explicitly avoids a source-code fix and instead recommends routing all HTTP(S) requests made by the server through an SSRF-safe proxy server as the primary mitigation. … Detailed patch versions, workarounds, and compensating controls in full report. |
