Attack Vectors

Accordion and Accordion Slider (slug: accordion-and-accordion-slider) is affected by a medium-severity authorization issue (CVE-2026-0727, CVSS 5.4). The risk comes from what an authenticated user can do after they already have a valid account.

An attacker with Contributor-level access or higher can potentially use the vulnerable plugin functionality to read and modify attachment metadata for any media item on the site. That includes items they did not upload themselves.

This attack does not require a victim to click anything and does not depend on complex conditions, which increases the likelihood that it could be used in real-world misuse scenarios once a low-privilege account is obtained.

Security Weakness

The plugin is vulnerable in versions up to and including 1.4.5 because it does not properly verify that a user is authorized to perform specific attachment-related actions in the functions wp_aas_save_attachment_data and wp_aas_get_attachment_edit_form.

In business terms, this is a permission control gap: users who should have limited editing rights may be able to access or change media attachment details across the site, instead of only the assets they should be allowed to manage.

Remediation: Update Accordion and Accordion Slider to version 1.4.6 or a newer patched version.

Technical or Business Impacts

If exploited, attackers can read and modify attachment metadata including file paths, titles, captions, alt text, and custom links. While this may sound “content-related,” it can create meaningful business exposure for marketing, compliance, and executive stakeholders.

Brand and campaign risk: Altered media titles, captions, or links can redirect visitors away from intended landing pages, disrupt attribution, reduce conversion rates, or create embarrassing public-facing inconsistencies across campaigns.

Compliance and privacy concerns: Unauthorized access to attachment details may expose sensitive information embedded in filenames or paths, or enable unauthorized changes to content presentation that conflicts with brand guidelines or regulated messaging requirements.

Operational impact: Investigating and restoring tampered media metadata can consume marketing and IT time, interrupt publishing workflows, and increase incident-response costs—especially if multiple assets are affected.

Similar Attacks

Authorization weaknesses in WordPress plugins are a common path for attackers to misuse legitimate accounts with low-to-mid permissions. Here are a few real examples of comparable “missing authorization” issues:

CVE-2024-27956 (WordPress: Bricks Builder) — an access control issue that raised serious security concerns for site owners relying on a page builder.

CVE-2023-2745 (WordPress: Elementor Pro) — a widely discussed vulnerability affecting a major plugin ecosystem, illustrating how plugin flaws can quickly become a business issue.

CVE-2021-25036 (WordPress: Yoast SEO) — an example of how plugin authorization problems can lead to unauthorized changes that impact site integrity and trust.
