Security readout for executives and security teams
Plain-English summary
A travel timeline app called My Location Travel Timeline (version 11.80) has a flaw in how it imports files. An attacker who can get the app to open a crafted import file could overwrite important internal files, which may let them run their own code or leak stored data. It matters mainly to individuals and organizations whose employees use this app on work-related devices.
Executive priority
Prioritize inventory of My Location Travel Timeline v11.80 on managed mobile devices, restrict untrusted file imports, and monitor vendor channels for a patched build before authorizing continued use.
Technical view
CVE-2026-30279 is a CWE-22 path traversal / arbitrary file overwrite in Squareapps LLC My Location Travel Timeline v11.80. The file import routine fails to properly constrain destination paths, allowing an attacker-supplied archive or import file to write outside the intended directory and clobber internal application files. Successful exploitation can lead to arbitrary code execution or information disclosure. CVSS 3.1 base score is 8.4 (AV:L/AC:L/PR:N/UI:N/C:H/I:H/A:H).
Likely exposure
Exposure is limited to installations of Squareapps LLC My Location Travel Timeline version 11.80, primarily a consumer-oriented mobile application. Enterprise exposure is most likely on employee-owned or unmanaged devices that handle travel data, or where the app has been sideloaded onto managed endpoints. Server-side or centralized exposure is not indicated by the sources.
Exploitation context
No public exploitation, KEV listing, or in-the-wild activity is cited in the source bundle. The CVSS vector indicates a local attack surface with no privileges or user interaction required, suggesting an attacker who can supply an import file to the app can trigger the flaw. A proof-of-concept issue is tracked in the Secsys-FDU AF_CVEs repository.
Researcher notes
Vector is local (AV:L) with no privileges or UI required, consistent with an on-device import flow where a malicious file lands via download, share sheet, or attached storage. CWE-22 plus "overwrite critical internal files" suggests directory traversal in a decompression or import parser. Affected product metadata in the CVE record is populated as "n/a," so definitive CPE mapping is unavailable; treat scoping as v11.80 only until the vendor confirms other builds. No patch, workaround, or KEV entry is cited in the bundle.
Mitigation direction
- Inventory devices running My Location Travel Timeline v11.80 and flag them for review.
- Restrict importing files from untrusted sources or unknown senders into the app.
- Monitor Squareapps LLC channels and app store listings for an official fixed release.
- Consider temporarily uninstalling the app on sensitive or corporate-managed devices until patched.
- Enforce mobile application management policies that block sideloaded or unvetted app versions.
Validation and detection
- Confirm installed version equals 11.80 via MDM or device inventory reports.
- Check vendor and app store release notes for a version above 11.80 addressing CVE-2026-30279.
- Review the Secsys-FDU AF_CVEs GitHub issue #28 for updated technical details and vendor response.
- Audit device logs for unexpected file modifications inside the app's sandbox after imports.
- Re-scan endpoints with mobile threat defense tooling once vendor guidance is published.
