MITRE ATT&CK
1 technique across 1 tactic: Privilege Escalation The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | Exploitation requires local access to a device running Samsung Flow prior to version 4.9.22.4 that is actively paired/connected to another device, plus the attack requirements indicated by AT:P in the CVSS 4.0 vector (a specific pairing/connection state must exist). The flaw stems from an incorrect default permission that lets a local attacker launch an arbitrary activity with Samsung Flow's privileges. Limiting factors: the attacker must already be local (AV:L), an active Samsung Flow connection to the target device must be established, and the condition-dependent attack requirement (AT:P) means exploitation is not reliable against arbitrary unpaired devices; impact is bounded to the connected system with low confidentiality/integrity effect only. |
| Impact | This is a genuinely low-priority issue, and the signals are consistent in pointing that way. The vendor-supplied CVSS 4.0 vector (AV:L/AC:L/AT:P/PR:N/UI:N) scores just 2.1, reflecting that an attacker must already have local access to the device and that specific attack requirements (AT:P) must be met for exploitation to succeed. Impact is confined to the subsequent (connected) system with only low confidentiality and integrity effect (SC:L/SI:L) and no impact on the vulnerable system itself or on availability. There is no EPSS score provided, no CISA KEV listing, and no public proof-of-concept - so exploitation probability signals are absent rather than contradictory. No SSVC decision data was supplied. One minor tension worth noting: the issue is tagged 'Information Disclosure,' but the description describes launching an arbitrary activity with Samsung Flow privileges, which is an improper-access-control / privilege issue rather than pure data disclosure; the low SC/SI impact is consistent with limited incidental disclosure. Overall this is a low-severity local privilege/access flaw, not a widespread remote-exploitation priority. |
| Exploit ScenarioDerived | A local attacker with code execution or an installed malicious app on a device paired via Samsung Flow leverages an incorrect default permission to launch an arbitrary activity that runs with Samsung Flow's privileges on the connected device. Because the attack is local and subject to specific attack requirements (AT:P), it requires the attacker to already be present on or adjacent to the paired device. No public exploit code has been identified at time of analysis. |

Alert meAnalysisAIv1 – Oct 12, 2026
Launching an arbitrary activity with Samsung Flow's own privileges is possible for a local attacker on a device running Samsung Flow prior to version 4.9.22.4, because the app ships with an incorrect default permission setting that exposes the capability to other local code on the device. Only users of the affected Samsung Flow builds on devices that are actually paired/connected to a counterpart device are exposed, and the resulting impact is bounded to the connected system with low confidentiality and integrity effect (vendor CVSS 4.0 base 2.1; our assessment CVSS 3.1 AV:L/AC:H/PR:N/UI:N/S:C/C:L/I:L/A:N). There is no indication of active exploitation (not in CISA KEV) and no public exploit identified at time of analysis, and the presence of the AT:P attack-requirement in the vendor vector means a specific pairing/connection state must exist before exploitation is even feasible.
RemediationAI
Upgrade Samsung Flow to version 4.9.22.4 or later through the Galaxy Store or Google Play; this is the vendor-released patch and the only definitive fix for the incorrect default permission. Because exploitation requires local code execution on the device and an active Samsung Flow pairing/connection, the practical interim controls are to keep Samsung Flow disconnected or uninstalled when cross-device continuity is not in use (removes the connected-device attack surface entirely, at the cost of losing Flow functionality) and to enforce a minimum Samsung Flow app version via MDM/EMM so that managed fleets cannot linger on builds below 4.9.22.4 (note that MDM enforcement does not block an already-installed older build on unmanaged personal devices). Reducing the number of untrusted or sideloaded apps on the device also lowers the pool of local callers that could attempt to launch the affected activity. No vendor-published workaround beyond upgrading is documented in the available advisory reference at https://security.samsungmobile.com/serviceWeb.smsb?year=2026&month=10.

Technical ContextAI · show details
Samsung Flow is a cross-device continuity app that links a phone to a PC, tablet, or other companion device for notification mirroring, file and clipboard transfer, screen sharing, and device unlocking. The flaw described is a permission/authorization defaulting problem in the Android application: an activity is reachable by other local components that should not be able to invoke it, and once invoked it executes in the Samsung Flow process context, inheriting that app's granted privileges on the connected device. This behavior maps to the incorrect-default-permissions class (CWE-276); note that no CWE was formally assigned in the source data. The CVSS 4.0 vector AV:L/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N is instructive: there is no privilege requirement and no user interaction, but the AT:P attack requirement and scope change (SC:L/SI:L) confirm that the vulnerable component is not directly damaged - the effect lands on the subsequently connected system. Our independent assessment aligns, rating it CVSS 3.1 AV:L/AC:H/PR:N/UI:N/S:C/C:L/I:L/A:N, with the higher AC and the S:C scope change reflecting that a live pairing/connection state is a precondition.
