Security readout for executives and security teams
Plain-English summary
CVE-2024-48776 is a high-severity information disclosure issue reported in Shelly com.home.shelly 1.0.4. The available record says a remote, unauthenticated attacker may obtain sensitive information through the firmware update process. The public data does not identify a vendor patch, affected CPEs, or confirmed real-world exploitation.
Executive priority
Treat this as a high-priority exposure review where Shelly components are present, especially if update services are reachable from untrusted networks. Urgency is driven by unauthenticated remote confidentiality impact, while patch direction remains unclear from the supplied sources.
Technical view
The CVE is mapped to CWE-306, missing authentication for a critical function. CVSS 3.1 is 7.5 with network attack vector, low complexity, no privileges, no user interaction, and high confidentiality impact only. The source bundle names com.home.shelly 1.0.4 and a firmware update process, but affected product metadata is incomplete.
Likely exposure
Likely exposure is limited to deployments using Shelly com.home.shelly 1.0.4 or the affected firmware update workflow. The CVE record’s affected vendor, product, CPE, and version metadata are listed as n/a, so inventory confirmation is required before scoping broadly.
Exploitation context
The bundle does not show CISA KEV listing or any cited evidence of active exploitation. The described attack is remote and unauthenticated, which raises concern, but available public details are sparse and should not be treated as proof of weaponized exploitation.
Researcher notes
The public record is thin: one GitHub report is referenced, affected metadata is n/a, and no vendor advisory is included. Avoid expanding affected scope beyond com.home.shelly 1.0.4 without additional evidence. Focus validation on authentication requirements and data exposure during firmware update handling.
Mitigation direction
Check official Shelly guidance for fixed versions or configuration mitigations.
Restrict firmware update interfaces to trusted networks where possible.
Remove public internet exposure for affected update workflows.
Inventory Shelly app/device versions and prioritize version 1.0.4 review.
Monitor for unusual firmware update traffic or unexpected information disclosure.
Validation and detection
Confirm whether com.home.shelly 1.0.4 exists in your environment.
Map any exposed firmware update endpoints or update services.
Review access controls around firmware update functionality.
Check logs for unexpected update requests or sensitive data access.
Track vendor advisories because no patch is named in the bundle.

CWE-306: Credential and account abuse lookup
Authentication and credential weaknesses can make valid-account abuse and credential telemetry useful review starting points. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
These fields come from the CVE record and ADP containers, not from Glexia's Take. They preserve time-varying source decisions such as CISA SSVC, KEV status, CVSS metrics, and provider references.
We collect every scored CVSS vector available in the official CNA and ADP containers. When more than one version is present, the table keeps the source vectors side by side instead of collapsing them into the highest score.

Missing Authentication for Critical Function
Missing Authentication for Critical Function represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
