Severity by source
AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:L/A:N
Network vector confirmed; AC:H because exploitation requires attacker-controlled OData endpoint; PR:L reflects authenticated OData session; C:H for credential disclosure, I:L for data injection, A:N confirmed.

A malicious or compromised OData service could disclose sensitive authentication information and inject untrusted data into the application, which may leads to a high impact on confidentiality and low impact on integrity and no impact on Availability.
AnalysisAI
Open redirect exploitation in SAP's python-pyodata library (versions before 1.11.2) allows a malicious or compromised OData service to capture sensitive authentication information transmitted by the client and inject untrusted data into the consuming application. Applications using pyodata that connect to externally controlled or attacker-reachable OData endpoints are at risk of credential disclosure and data integrity compromise. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires the vulnerable application to be configured to connect to an OData service endpoint that the attacker controls or has compromised. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The NVD CVSS 3.1 score of 5.9 (Medium) reflects the realistic threat model accurately: AV:N places the attack over the network, AC:H signals that exploitation requires a specific precondition - the target application must be pointed at a malicious or already-compromised OData service endpoint - and PR:L indicates the application connecting to the OData service must itself be operating with at least low-privilege credentials, consistent with authenticated OData access. … 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 | The primary fix is to upgrade pyodata to version 1.11.2 or later via pip: 'pip install --upgrade pyodata>=1.11.2'. … Detailed patch versions, workarounds, and compensating controls in full report. |
