{"cve":"CVE-2026-33046","nvd":{"published":"2026-03-23T23:17:12.520","modified":"2026-06-17T10:36:51.863","status":"Analyzed","description":"Indico is an event management system that uses Flask-Multipass, a multi-backend authentication system for Flask. In versions prior to 3.3.12, due to vulnerabilities in TeXLive and obscure LaTeX syntax that allowed circumventing Indico's LaTeX sanitizer, it is possible to use specially-crafted LaTeX snippets which can read local files or execute code with the privileges of the user running Indico on the server. Note that if server-side LaTeX rendering is not in use (ie `XELATEX_PATH` was not set in `indico.conf`), this vulnerability does not apply. It is recommended to update to Indico 3.3.12 as soon as possible. It is also strongly recommended to enable the containerized LaTeX renderer (using `podman`), which isolates it from the rest of the system. As a workaround, remove the `XELATEX_PATH` setting from `indico.conf` (or comment it out or set it to `None`) and restart the `indico-uwsgi` and `indico-celery` services to disable LaTeX functionality.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":7.7},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-22","CWE-78"],"references":["https://github.com/indico/indico/commit/0adb70f0ed66e129361d447868f5f3eb90dc5e96","https://github.com/indico/indico/commit/1dbb12525b3de14229bf4d1ae192988068f975f6","https://github.com/indico/indico/commit/5f24d23ce9c4b0e4b68b3d0b58987a948fc57c8a","https://github.com/indico/indico/commit/fb169ced710c30cf792ce4b9f48688db0633cfd8","https://github.com/indico/indico/releases/tag/v3.3.12"],"products":["cern:indico"],"source":"nvd","synced_at":"2026-10-19T22:26:19.218427112+00:00"},"epss":{"cve":"CVE-2026-33046","score":0.00796,"percentile":0.56476,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-rm2q-f7jv-3cfp","url":"https://osv.dev/vulnerability/GHSA-rm2q-f7jv-3cfp","summary":"Indico discloses local files resulting in Remote Code Execution through LaTeX injection ","modified":"2026-07-13T07:26:43.762604006Z","packages":[{"ecosystem":"PyPI","name":"indico","purl":"pkg:pypi/indico","ranges":["<3.3.12"],"fixed":["3.3.12"]}]},{"id":"PYSEC-2026-2184","url":"https://osv.dev/vulnerability/PYSEC-2026-2184","summary":"","modified":"2026-07-13T07:15:31.500157980Z","packages":[{"ecosystem":"PyPI","name":"indico","purl":"pkg:pypi/indico","ranges":["<3.3.12"],"fixed":["3.3.12"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
