Weak authentication in Microsoft Windows Search Component allows an authorized attacker to disclose information locally.
AnalysisAI
Information disclosure in the Microsoft Windows Search Component allows a locally authenticated low-privileged attacker to bypass weak authentication controls and access sensitive indexed content outside their authorized scope. Affected systems span Windows Server 2012 through Server 2025 and Windows 10/11 across all current supported versions, representing an exceptionally broad exposure surface. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid low-privileged local account on the target Windows system, as confirmed by the CVSS PR:L metric and the description's reference to 'an authorized attacker.' The attack is strictly local (AV:L) - remote exploitation without a prior foothold is not possible. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N) scores 5.5 Medium, reflecting a locally-constrained flaw with high confidentiality impact but no integrity or availability consequence. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A low-privileged user on a shared Windows terminal server or multi-user endpoint abuses the weak authentication in the Windows Search Component to query the search index and retrieve file names, content snippets, or metadata from documents belonging to other users or restricted system paths - for example, recovering cached credentials, sensitive HR files, or configuration data indexed from administrative shares. Because attack complexity is low and no user interaction is required, the attacker executes this from any local command prompt or scripted call once a valid account is obtained. … |
| Remediation | Microsoft has released security updates for all affected versions. … Detailed patch versions, workarounds, and compensating controls in full report. |
