Security readout for executives and security teams
Plain-English summary
CVE-2026-25379 affects the WordPress StreamVid theme before version 6.8.6. It can allow an unauthenticated remote attacker to include local files through unsafe PHP include/require handling. The CVSS score is 8.1, reflecting potential confidentiality, integrity, and availability impact, although exploitation complexity is rated high.
Executive priority
Prioritize remediation for public WordPress sites running StreamVid before 6.8.6. The business risk is high because successful exploitation could expose files or affect site integrity, but current public sources do not confirm active exploitation.
Technical view
The issue is classified as CWE-98, improper control of filenames used in PHP include/require statements. Public metadata describes it as PHP Local File Inclusion in jwsthemes StreamVid, affecting versions earlier than 6.8.6. The CVSS vector is AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H. No CISA KEV listing is reported in the provided sources.
Likely exposure
Exposure is limited to WordPress sites using the jwsthemes StreamVid theme before 6.8.6. Internet-facing WordPress deployments are the primary concern. Sites not using this theme, or using version 6.8.6 or later, are not indicated as affected by the supplied sources.
Exploitation context
The vulnerability is remotely reachable and requires no privileges or user interaction, but attack complexity is high. The provided sources do not state active exploitation, public exploit availability, or specific attack prerequisites beyond the affected theme version.
Researcher notes
There is a wording mismatch: the CWE label references PHP remote file inclusion, while the description states local file inclusion. Treat the issue as source-confirmed LFI unless vendor details clarify otherwise. Public data is limited to CVE metadata and Patchstack’s database entry.
Mitigation direction
- Inventory WordPress sites for the StreamVid theme.
- Update StreamVid to version 6.8.6 or later if available.
- Check Patchstack and vendor guidance for current remediation instructions.
- Remove the theme if it is unused or cannot be updated.
- Maintain tested backups before making WordPress theme changes.
Validation and detection
- Confirm whether StreamVid is installed on each WordPress site.
- Record the installed StreamVid version.
- Verify the version is 6.8.6 or newer.
- Review web logs for suspicious file access attempts.
- Recheck Patchstack and CVE records for updated guidance.

Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion')
Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
