1 technique across 1 tactic: Defense Evasion

The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up.

Exploitation Conditions

The specific prerequisite is the insecurely-permissioned, exported ShortcutDispatchActivity in vokibot versionCode 14: because the component lacks proper access control, any caller on the device can dispatch a shortcut and thereby trigger automated actions another user configured. Exploitation realistically requires the attacker to be able to send an intent to that activity - in practice a malicious or compromised app co-located on the same device, or an attacker-controlled shortcut invocation. Limiting factors: the flaw is tied specifically to versionCode 14 of a single F-Droid app, and despite the CVSS AV:N rating the Android component model makes same-device/local attacker presence the likely realistic precondition; this should be confirmed with the vendor advisory.

Impact

Signals conflict and must be weighed carefully. The input CVSS vector (AV:N/AC:L/PR:N/UI:N) yields 9.1 and implies remote, unauthenticated, network-reachable exploitation, but the vulnerable component - an Android 'ShortcutDispatchActivity' in the F-Droid app net.canvoki.vokibot with CWE-284 (Improper Access Control / insecure permissions) - points to an exported-component / inter-app access flaw that is realistically triggered locally on the device by another installed app or shortcut rather than across the network; this AV:N-versus-local discrepancy should be verified against the vendor advisory before treating it as a remote network bug. The vuln.today decision label is act_now, yet EPSS is only 0.17% (6th percentile), it is NOT in CISA KEV, and no working exploit code is identified - so the high priority label appears driven by the raw 9.1 CVSS rather than by evidence of widespread exploitation. PR:N (unauthenticated) is consistent with the 'unauthorized attackers' wording. Net assessment: a genuine access-control weakness, but the real-world risk is bounded by a tiny deployment footprint and the likely need for local/same-device attacker presence; the act_now label reflects severity scoring, while the low EPSS and absence of KEV/PoC suggest no observed mass exploitation.

Exploit ScenarioDerived

A malicious or untrusted application installed on the same Android device sends a crafted intent to vokibot's improperly-permissioned ShortcutDispatchActivity, which dispatches a shortcut without verifying the caller's authorization. This lets the attacker invoke automated actions that another user had configured in the bot, without their consent. No public exploit code is identified, so this remains a described weakness rather than a demonstrated weaponized attack.

AnalysisAIv1 – Oct 30, 2026

The canvoki vokibot Android app at versionCode 14 exposes its ShortcutDispatchActivity without adequate access control, so a caller on the same device can dispatch a shortcut and thereby fire automated actions that another user configured. Our assessment places the realistic threat as a local, on-device attacker (for example a malicious or compromised co-installed app able to send an intent to the activity), with high integrity impact and no confidentiality impact; the originally published CVSS of 9.1 with AV:N should be reconciled against that local component-model precondition. The EPSS score is low at 0.17% (6th percentile) and no confirmed active exploitation or public exploit code was identified at the time of analysis, although the prioritization label is act_now, and the flaw is scoped narrowly to a single F-Droid app build.

RemediationAI

No vendor-released patch or fixed versionCode was identified at the time of analysis, so there is no exact upgrade target to cite; check https://github.com/vokimon/vokibot and the advisory at https://github.com/FFG0d/fdroid-android-advisories/blob/main/advisories/CVE-2026-107017.md for a corrected build before installing or reinstalling the app. For users already on versionCode 14, the actionable compensating controls follow directly from the flaw: rebuild the APK with ShortcutDispatchActivity set to android:exported="false" or guarded by a signature-level custom permission, which closes the intent path but breaks any legitimate cross-app shortcut invocation the feature was designed for; restrict the device to trusted app sources and avoid co-installing untrusted or sideloaded apps alongside vokibot, which reduces but does not eliminate exposure to a malicious co-resident app; and, where shortcut automation is not needed, uninstall vokibot or remove its configured automated actions until a fixed build is available, accepting the loss of the app's intended functionality.

Technical ContextAI · show details

vokibot is a small Android application distributed through F-Droid (package net.canvoki.vokibot, upstream at github.com/vokimon/vokibot), and the flaw sits in its Android component model rather than in a network service. ShortcutDispatchActivity is an activity that dispatches shortcuts and, in versionCode 14, it is reachable by callers that should not be able to invoke it - the classic improper access control pattern captured by CWE-284. Android components are either exported (reachable by any other app on the device via an Intent) or protected by a permission; when an exported activity handling shortcut dispatch lacks a permission check or caller verification, any co-resident app can construct the matching intent and cause the app to execute the automated actions configured by the user. The assessed vector is CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N, reflecting the local nature of intent-based invocation and an integrity-only impact, which is narrower than the published AV:N/C:H/I:H scoring. The exact intent extras and validation logic required to reach the dispatch path are not described in the available sources, and the vendor advisory referenced in the FFG0d F-Droid advisories repository should be consulted to confirm the precise precondition.

DescriptionCVE.org

Insecure permissions in the ShortcutDispatchActivity component of canvoki versionCode 14 allows unauthorized attackers to arbitrarily trigger another user's configured automated actions.

Executive ViewAI

Why It Matters

The canvoki vokibot Android app (versionCode 14) has a critical access control flaw that allows a malicious app on the same device to trigger user-configured shortcuts without authorization. This primarily threatens the integrity of automated actions for users who have installed the app, though the narrow scope and lack of active exploitation limit broader organizational impact.

Business Impact: Medium
Compensating Controls

No vendor-released patch identified at time of analysis. Interim mitigations include uninstalling or disabling the app on affected devices, restricting app installations via MDM to approved applications only, and enforcing device policies that limit inter-process communication between apps (e.g., using work profiles or app sandboxing).
