SQL Injection in Android Contacts Provider Can Expose the Contacts Database

In Contacts Provider, there is a possible way to access the contacts database due to SQL injection. This could lead to local information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation.

• Android, product Android: the normalized record marks version 17 as affected and sets the default status to unaffected for versions not otherwise listed.
• The Android bulletin states that devices running Android 17 with security patch level 2026-07-01 or later address all issues in those release notes.
• Devices in the affected branch without patch level 2026-07-01 should be treated as potentially affected until OEM or carrier status is confirmed. The available evidence does not define affected boundaries for other Android branches.

The confirmed defect is SQL injection in Contacts Provider. SQL injection normally occurs when input is incorporated into a database query without adequate separation between data and query syntax; however, the record does not identify the specific provider operation, URI, parameter, query construction, or validation failure, so those implementation details remain unknown. An attacker-controlled value is the implied input class, but the exact entry point has not been disclosed. The confirmed outcome is possible access to the contacts database and local information disclosure. The supplied exploitability assessments disagree on whether the issue is network-reachable without privileges or locally reachable with low privileges, so neither reachability model should be treated as independently confirmed.

The record states that exploitation does not require user interaction or additional execution privileges. One supplied assessment models network reachability without privileges, while another models local access with low privileges, so the actual reachability remains unresolved. The Android bulletin classifies the issue as information disclosure. That bulletin also states that it had no reports of active customer exploitation or abuse for the newly reported issues within the scope of the bulletin. The supplied record does not identify a public exploit; this does not prove that no public exploit exists.

The confirmed impact is possible disclosure of data in the contacts database. This could expose contact information stored on the device and affect privacy or the scope of data an organization must protect. One supplied assessment models high confidentiality, integrity, and availability impact, but the vulnerability description confirms only information disclosure; modification or service disruption should not be treated as established outcomes. The practical privilege and reachability scope also remain unresolved because the supplied assessments disagree on network and local access.

The issue could expose data stored in contacts databases on Android devices, affecting user privacy and incident-response obligations. Exposure may create organizational risk when contact records contain internal, customer, or partner information. The record does not establish that data was actually accessed or exfiltrated, so it should not be treated as evidence of a confirmed breach. Organizations should prioritize identifying unpatched devices and assessing whether Contacts Provider can be reached in their environments.

1. Apply the OEM or carrier update that brings Android 17 to security patch level 2026-07-01 or later. The Android bulletin confirms that this patch level addresses the issues in the relevant release notes.
2. Recheck the Android version and security patch level after updating, and verify that the device received the intended update rather than only confirming that an update was downloaded.
3. If a device cannot reach the required patch level, continue treating it as potentially affected and coordinate with the OEM or carrier on an update path. No separate workaround is specified in the supplied record or the consulted Android bulletin.

1. Inventory Android devices, operating-system versions, and current security patch levels.
2. Compare each device with the affected branch and confirm that it has received the security patch level specified for remediation.
3. Where suitable telemetry exists, review unusual activity involving access to Contacts Provider data. Treat this only as precautionary monitoring because no specific indicator of compromise is provided.
4. Do not treat the absence of anomalous logs as proof of safety. Version and patch-level verification should remain the primary check.
