Contributor PHP Object Injection in Photo Gallery by 10Web <= 1.8.46 versions.
AnalysisAI
PHP object injection in the Photo Gallery by 10Web WordPress plugin (versions up to and including 1.8.46) allows an authenticated user with Contributor-level privileges to pass crafted serialized data into a plugin code path that calls unserialize(), which under CVSS 3.1 scores 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H). Successful exploitation can corrupt or disclose data and, if a usable PHP gadget chain exists in the plugin, WordPress core, or another active plugin, can escalate to arbitrary code execution on the web server; no user interaction is required once the low-privileged account exists. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires an authenticated WordPress user with at least Contributor-level privileges (per the vulnerability title and PR:L), reaching a plugin code path that deserializes attacker-controlled input via unserialize(). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, base 8.8) indicates a network-reachable, low-complexity flaw requiring only low-level authentication and no user interaction, with high impact to confidentiality, integrity, and availability - consistent with a PHP Object Injection (CWE-502) that can escalate to remote code execution when a usable gadget chain is present in the plugin, WordPress core, or another loaded plugin. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | The intelligence provided does not include an exact fixed version, so no vendor-released patch version can be confirmed at time of analysis; administrators should check the Patchstack advisory (https://patchstack.com/database/wordpress/plugin/photo-gallery/vulnerability/wordpress-photo-gallery-by-10web-plugin-1-8-46-php-object-injection-vulnerability?_s_id=cve) and the plugin's wordpress.org page for a release newer than 1.8.46 and deploy it as soon as it is published, testing on staging first since gallery shortcodes and stored settings can change between releases. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory every WordPress installation running Photo Gallery by 10Web at version 1.8.46 or earlier, and where the plugin is not business-critical, deactivate and remove it immediately; where it is required, restrict access by removing Contributor and higher roles from all untrusted or externally sourced accounts and disable open user registration. …
