PYSEC-2026-1274 Copier safe template has arbitrary filesystem read access via symlinks when _preserve_symlinks: false

Impact Copier suggests that it's safe to generate a project from a safe template, i.e. one that doesn't use unsafe features like custom Jinja extensions which would require passing the --UNSAFE,--trust flag. As it turns out, a safe template can currently include arbitrary files/directories outsid...

PYSEC-2026-1272 Copier safe template has arbitrary filesystem write access via directory symlinks when _preserve_symlinks: true

Impact Copier suggests that it's safe to generate a project from a safe template, i.e. one that doesn't use unsafe features like custom Jinja extensions which would require passing the --UNSAFE,--trust flag. As it turns out, a safe template can currently write to arbitrary directories outside the...

PYSEC-2026-1518 LangChain Vulnerable to Template Injection via Attribute Access in Prompt Templates

Context A template injection vulnerability exists in LangChain's prompt template system that allows attackers to access Python object internals through template syntax. This vulnerability affects applications that accept untrusted template strings not just template variables in ChatPromptTemplate...

PYSEC-2026-1273 Copier's safe template has filesystem write access outside destination path

Impact Copier suggests that it's safe to generate a project from a safe template, i.e. one that doesn't use unsafe features like custom Jinja extensions which would require passing the --UNSAFE,--trust flag. As it turns out, a safe template can currently write files outside the destination path...

PYSEC-2026-1271 Copier's safe template has arbitrary filesystem read/write access

Impact Copier's current security model shall restrict filesystem access through Jinja: - Files can only be read using % include ... %, which is limited by Jinja to reading files from the subtree of the local template clone in our case. - Files are written in the destination directory according to...

PYSEC-2026-1471 Jinja2 vulnerable to sandbox breakout through attr filter selecting format method

An oversight in how the Jinja sandboxed environment interacts with the |attr filter allows an attacker that controls the content of a template to execute arbitrary Python code. To exploit the vulnerability, an attacker needs to control the content of a template. Whether that is the case depends o...

PYSEC-2026-1804 Azure PromptFlow remote code execution related to Jinja templates

Improper isolation or compartmentalization in Azure PromptFlow allows an unauthorized attacker to execute code over a network...

PYSEC-2026-1475 Jinja has a sandbox breakout through indirect reference to format method

An oversight in how the Jinja sandboxed environment detects calls to str.format allows an attacker that controls the content of a template to execute arbitrary Python code. To exploit the vulnerability, an attacker needs to control the content of a template. Whether that is the case depends on th...

PYSEC-2026-1338 Remote Code Execution Vulnerability via SSTI in Fides Webserver Jinja Email Templating Engine

Summary The Email Templating feature uses Jinja2 without proper input sanitization or rendering environment restrictions, allowing for Server-Side Template Injection that grants Remote Code Execution to privileged users. A privileged user refers to an Admin UI user with the default Owner or...

PYSEC-2026-1447 Insecure Jinja2 templates rendered in Haystack Components can lead to RCE

Impact Haystack clients that let their users create and run Pipelines from scratch are vulnerable to remote code executions. Certain Components in Haystack use Jinja2 templates, if anyone can create and render that template on the client machine they run any code. Patches The problem has been fix...

PYSEC-2026-1631 Potentially untrusted input is rendered as HTML in final output

Impact All users of mjml-python who insert untrusted data into mjml templates unless that data is checked in a very strict manner. User input like script would be rendered as in the final HTML output. The attacker must be able to control some data which is later injected in an mjml template which...

PYSEC-2026-1949 Privilege escalation for users that can access mock configuration

The Mock software contains a vulnerability wherein an attacker could potentially exploit privilege escalation, enabling the execution of arbitrary code with root user privileges. This weakness stems from the absence of proper sandboxing during the expansion and execution of Jinja2 templates, whic...
