Is CVE-2025-48633 (Android Framework Information Disclosure) being exploited in the wild?

By NHI Mgmt Group Editorial Team Updated October 19, 2026 Domain: Threats, Abuse & Incident Response

Yes. CISA added CVE-2025-48633 to its Known Exploited Vulnerabilities catalogue on 2 December 2025, which it does only when there is reliable evidence of active exploitation. CISA has not linked it to known ransomware campaigns. Android Framework contains an unspecified vulnerability that allows for information disclosure. Any organisation running the affected product should treat remediation as urgent.

What makes an exploited Android Framework disclosure urgent?

An exploited information-disclosure flaw in a core mobile OS layer changes prioritisation because exposure is no longer hypothetical. The practical question is not whether the device “looks healthy,” but whether it could already have leaked data, identifiers, or other sensitive state to an attacker who used the weakness before remediation.

For mobile fleets, the first step is confirming where Android Framework exposure exists across managed devices, tablets, and user-owned devices that access enterprise mail, chat, VPN, or SSO. The Mobile Device Security Guide is useful here because exposure analysis depends on device inventory, enrolment status, and whether the organisation can actually enforce remediation.

Why “information disclosure” matters even without confirmed ransomware

Information disclosure is often treated as lower severity than code execution, but in an exploited mobile platform flaw it can still be the first step in credential theft, session hijack, targeted phishing, or follow-on compromise. The immediate loss is usually visibility into data that should not have been exposed, but the downstream risk can be account compromise or broader access to enterprise systems the device reaches.

This is why active exploitation should trigger urgent triage even when there is no ransomware linkage. The issue is the confirmed exploitation path, not the presence of a named extortion campaign. When the same device also carries corporate mail, app sessions, or device-bound tokens, the security impact can extend beyond the handset itself.

The broader lesson is captured by the Zero-Day and Exploited Vulnerabilities Guide, which frames KEV-listed issues as time-sensitive remediation problems rather than routine patch items.

How to respond when patching is delayed

If immediate patching is not possible, reduce exposure quickly by restricting affected devices from the most sensitive access paths, increasing monitoring for unusual sign-ins or app activity, and forcing reauthentication where session leakage is plausible. Because information disclosure can expose secrets indirectly, you should also assess whether the device held reusable credentials, tokens, or cached sessions that need rotation or invalidation.

Use the Vulnerability Management Guide to align the response with KEV-based prioritisation, exception handling, and verification rather than ad hoc patch chasing. The right question is whether the remediation is closed, verified, and tracked to completion, not whether the advisory has been acknowledged.

Risk and Threat Considerations

Exploited mobile platform disclosures can turn a single vulnerable device into a source of credential exposure, session theft, or sensitive-data leakage across corporate apps. The main danger is not only the disclosed content itself, but the trust that a compromised device may still hold in enterprise access flows.

Failure mechanism: An attacker abuses the Android Framework flaw before remediation, extracts information that should have remained local or protected, and uses that exposure to support account abuse, targeted follow-on access, or further compromise.

Impact: Organisations may need to assume device-level data exposure, investigate whether linked accounts or sessions were affected, and treat the device as an access-risk source until exposure is contained and credentials are reviewed.

Standards & Framework Alignment

This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.

NIST CSF 2.0, CIS Controls v8, OWASP ASVS and NIST SP 800-53 Rev 5 set the technical controls, while ISO/IEC 27001:2022 defines the regulatory obligations.

Framework	Control / Reference	Relevance
NIST CSF 2.0	ID.RA-01 — Asset Vulnerabilities Are Identified And Managed	Exploit status makes vulnerability identification and prioritisation central.
Recommendation — Prioritise KEV-listed mobile flaws for immediate remediation and exception tracking.
CIS Controls v8	CIS-7 — Continuous Vulnerability Management	The question is about active exploitation and urgent vulnerability handling.
Recommendation — Track exploited Android flaws through continuous scanning, prioritisation, and remediation verification.
OWASP ASVS	V13 — Configuration	Mobile app and device exposure often depends on secure configuration and patch state.
Recommendation — Verify device and application configuration against known-exploited mobile vulnerability exposure.
ISO/IEC 27001:2022	A.8.8 — Management of technical vulnerabilities	Active exploitation requires formal vulnerability management and timely remediation.
Recommendation — Apply technical vulnerability management controls to accelerate remediation and evidence closure.
NIST SP 800-53 Rev 5	SI-2 — Flaw Remediation	A KEV-listed Android flaw requires disciplined remediation and verification.
Recommendation — Use flaw remediation controls to patch, mitigate, and verify closure of the exploited issue.

Practitioner Guidance

What to verify: Confirm which Android devices are in scope, whether they are managed, and whether they can be remediated through policy or require user action. Do not assume the fleet is safe because only a subset is internet-facing; mobile exposure often comes from ordinary enterprise app use.

Decision rule: If the affected device has access to mail, messaging, VPN, or SSO, prioritise patching and access review before routine maintenance work. If patching must wait, treat the device as potentially exposed and narrow its access until remediation is complete.

Practitioner takeaway: For an exploited mobile OS flaw, urgency comes from what the device could have revealed and enabled, not just from the vulnerability label.
