Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: A Cross-Site Scripting (XSS) flaw in **Movary**. π **Consequences**: Attackers can inject malicious scripts, compromising user sessions and data integrity. It stems from insufficient input validation.
Q2Root Cause? (CWE/Flaw)
π‘οΈ **Root Cause**: **CWE-20** (Improper Input Validation). π **Flaw**: The application fails to properly sanitize the `categoryCreated` parameter, allowing raw script execution in the browser.
Q3Who is affected? (Versions/Components)
π₯ **Affected**: Users running **Movary** versions **< 0.70.0**. π·οΈ **Vendor**: Lee Peuker. π¦ **Product**: Personal movie review program.
Q4What can hackers do? (Privileges/Data)
π **Hackers Can**: Execute arbitrary JavaScript in victims' browsers. π΅οΈ **Impact**: Steal cookies, hijack accounts, or redirect users. High impact on Confidentiality (C:H) and Integrity (I:H).
Q5Is exploitation threshold high? (Auth/Config)
βοΈ **Threshold**: **Low**. π **Network**: Remote (AV:N). π **Auth**: None required (PR:N). π±οΈ **UI**: Requires User Interaction (UI:R) to trigger the payload.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π« **Public Exp**: **No**. π **PoC**: None listed in the advisory. β οΈ **Status**: Theoretical risk until a PoC is released or wild exploitation occurs.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for Movary instances. π§ͺ **Test**: Inject script payloads into the `categoryCreated` field. π **Observe**: Check if the script executes in the response without sanitization.
Q8Is it fixed officially? (Patch/Mitigation)
β **Fixed**: **Yes**. π¦ **Patch**: Upgrade to **version 0.70.0** or later. π **Ref**: [GitHub Advisory](https://github.com/leepeuker/movary/security/advisories/GHSA-v877-x568-4v5v).
Q9What if no patch? (Workaround)
π οΈ **Workaround**: If unpatched, implement **WAF rules** to block script tags in `categoryCreated`. π« **Manual**: Strictly validate and encode all user inputs server-side before rendering.
Q10Is it urgent? (Priority Suggestion)
β° **Urgency**: **High Priority**. π **Action**: Patch immediately. Although UI interaction is needed, the lack of authentication and remote nature makes it a critical risk for public-facing instances.
