# CVE-2026-1115: parisneo/lollms vulnerable to stored XSS in the social feature

**Signal:** Critical and remotely reachable. No known exploitation yet, but it is network-reachable without credentials. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Not in CISA KEV , but CISA’s SSVC assessment records a public proof-of-concept, so attack code exists.
- EPSS 1.3% , percentile 69: FIRST’s model estimates a 1.3% chance of exploitation activity in the next 30 days, higher than 69% of all scored CVEs (moderate). EPSS is a probability, not a verdict.
- Needs a user to click or open something. Phishing makes that realistic, but it is not wormable.
- Only applies if your dependency tree includes lollms (PyPI) < 2.2.0, fixed in 2.2.0 . Check your lockfile, including transitive dependencies.

## What it is

A Stored Cross-Site Scripting (XSS) vulnerability was identified in the social feature of parisneo/lollms, affecting the latest version prior to 2.2.0. The vulnerability exists in the createpost function within backend/routers/social/init.py, where user-provided content is directly assigned to the DBPost model without sanitization. This allows attackers to inject and store malicious JavaScript, which is executed in the browsers of users viewing the Home Feed, including administrators. This can lead to account takeover, session hijacking, and wormable attacks. The issue is resolved in version 2.2.0.

## Affected packages

- PyPI `lollms` < 2.2.0 → fixed: 2.2.0

## Affected products (CVE record)

- parisneo parisneo/lollms: unspecified < 2.2.0

## Severity

- @huntr_ai CVSS 3.0: 9.6 `CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H`
- GitHub CVSS 3.1: 9.6 `CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation poc , automatable no , technical impact total .
- FIRST EPSS (model of 2026-10-21): 1.26% probability of exploitation activity in the next 30 days; percentile 69.
